Barnard's Star's Planet Added!

The archive has added data for Barnard's star b (a.k.a. Barnard b), a planet discovered orbiting the closest single star to our Sun. The system is located just six light-years from Earth and the planet is 20 times closer to its star than Mercury is to the Sun—which makes it too hot to support liquid water.

Learn more about the discovery in the discovery paper and the European Space Observatory (ESO) news release, or go straight to the archive's Barnard's star System Overview page for the data. The new planet has also been added to the Planetary Systems and Planetary Systems Composite Data tables.

A Six-tacular Update!

Six is our lucky number this week, with six new planets and new spectra for six planets. The new spectra show evidence of sulfur in the atmospheres of two of the planets, which can help provide information about the formation location and evolutionary history of the planets.

Check out the System Overview pages for L 98-59 d and GJ 3470 b, as well as the University of Wisconsin news release for GJ 3470 b. The other planets with new spectra that have been added to our Atmospheric Spectroscopy Table are GJ 486 b, TOI-836 c, WASP-39 b, and L 98-59 c.

Five of this week's new spectra were taken by JWST for planets that are either sub-Neptunes or super-Earths, which establish a new sample of spectra for small planets that can be used to help researchers find planets that are likely to have atmospheres and are potentially habitable.

New Planets and Parameters

The six planets added this week are HD 222237 b, HIP 67522 c, TOI-2714 b, TOI-2981 b, TOI-4562 c, and TOI-4914 b. There are also new parameters for GJ 486 b, HIP 116454 (K2-2 b), and WASP-39 b.

Improved Pre-generated Plots

Our pre-generated plots now offer the same look, feel, and interactivity as the upgraded scatter plots and histograms served through the Planetary Systems tables!

The archive offers these ready-made plots to the community for use in presentations, reports, and other displays. The static plots—those displayed on the Exoplanet Plots web page—are updated whenever the archive's holdings are updated. The plots are already rendered in our new built-in Presentation theme, so just click, copy, and paste the image directly into your slides.

Other enhancements in today's release include:

  • They're interactive! From the Exoplanet Plots page, click the Interactive Plot link under the plot you want to explore to access more tools, including pan, zoom, adding errorbars, and adjusting symbol sizes and colors.
  • They link to more data! Mouse over a data point for at-a-glance information about that object, or click on it to view its System Overview page.
  • Includes solar system planets! Some plots, such as Planet Mass/Mass*sin(i) vs. Orbital Period and Planet Radius vs. Planet Mass, now include solar system planets.
  • New color palettes and themes! Choose from six color palettes and four themes, including a Dark theme.

To access the Exoplanet Plots page, click on Tools in our site navigation menu and select Pre-generated Plots, or click the Plots button in the news slider of our home page.

Four Planets Added, One Demoted

This week's new data include four planets: HD 21520 b, TOI-2379 b, TOI-2384 b, and TOI-3568 b. There are also new parameter data for 28 planets. Check the planet's respective System Overview page or browse the Planetary Systems and Planetary Systems Composite Data tables.

The demoted planet, BD-00 4475 b, is now dispositioned as a False Positive Planet because its mass exceeds 30 Jupiter masses according to new published data. The object's new status is reflected on the BD-00 4475 System Overview page, which will continue to serve its data. The Exoplanet Criteria for Inclusion in the Archive page explains how the archive determines which objects to include in its holdings.

Atmospheric Spectroscopy 2.0: Now With Direct Imaging Spectra!

Our Atmospheric Spectroscopy Table now serves spectra for directly imaged (DI) planets! To kick off this latest update, we've loaded the table with 37 spectra for 12 DI planets, with most of the spectra taken by JWST. These planets are 2MASS J12073346-3932539 b (a.k.a. TWA 27 b), VHS J125601.92-125723.9 b, 51 Eri b, GQ Lup b, HIP 65426 b, HR 8799 b, c, d, & e, PDS 70 b & c, and bet Pic b. There are also new transmission spectra for TOI-836 b, V1298 Tau b, and WASP-107 b.

This plot, generated by the Atmospheric Spectroscopy Table, visualizes four direct imaging spectra taken by JWST of VHS J1256-1257 b.

Some other improvements include:

  • The table's user interface now reflects recent changes to the Firefly framework, upon which the service is built.
  • The new DI spectra support has added more data columns and support for converting direct imaging values. Click the User Guide tab in the table's interface to view the updated documentation.
  • The spectrum type previously called emission is now referred to as eclipse.
  • The Planetary Systems tables have a new column for the Number of Direct Imaging Spectroscopy Measurements: pl_ndispec

These elements—and more—are listed and described on our Archive 2.0 Release Notes page. Or, just start working with the table now!

One final note: Is the table missing your favorite direct imaging spectrum? Let us know and we'll add it!

Ten Planets and 300,000 Exozodiacal Dust Levels

We've added 10 new planets this week, as well as new parameter sets for an additional 18 planets. One of this week's new planets (TOI-4336 A b) is a sub-Neptune in its host star's habitable zone, and its host star is part of a triple star system.

The other new planets are EPIC 248030407 b (ITG 15 b), G 196-3 b, HIP 77900 b, TIC 139270665 b & c, 2MASS J03590986+2009361 b, 2MASS J11011926-7732383 b, 2MASS J11550336-7919147 b, and 2MASS J21265040-8140293 b. Click on their names to go directly to their System Overview pages, or browse all system parameters in the archive (including this week's new sets) with the Planetary Systems and Planetary Systems Composite tables.

We've also added spectral data for TOI-1268 b to our Atmospheric Spectroscopy Table.

Planetary Systems Table Update! We've added new, non-default parameters to the Planetary Systems Composite Data Table for measuring the angular separation on the sky between a star and planet: pl_angsep, pl_angseperr1 (positive uncertainty), pl_angseperr2 (negative uncertainty), pl_angseplim (limit), and pl_angsep_reflink (reference).

Because these parameters are not defaults, they must be added to the table through the Select Columns interface. The following image indicates where to find the parameters; to add them, check the box(es) to display that column in the PSCompPars table and then click Update.

New Contributed Data: Exozodiacal Dust Measurements

The Hunt for Observable Signatures of Terrestrial planetary Systems (HOSTS) survey for exozodiacal dust concluded that the majority of Sun-like stars have relatively low habitable zone dust levels. The archive now hosts a subset of data from Ertel et al. (2020): a random draw of 300,000 exozodiacal dust levels from the best-fit luminosity function of HOSTS survey data. These data can be used to model the results of potential future missions, such as the Habitable Worlds Observatory (HWO).

Scroll to the Exozodiacal Dust section of our Contributed Data page to access the data and documentation.

(While we're on the topic of HWO, have you checked out our HWO ExEP Precursor Science Stars table?)

Know Thy Star: Introducing the New Stellar Hosts Table

Our newest interactive table, Stellar Hosts, provides a single access point to all stellar parameters of stars in systems with confirmed planets that are in the Exoplanet Archive. With this interface, you may browse stellar parameters of planetary systems that are in our Planetary Systems and Planetary Systems Composite Data tables, as well as stellar parameters that were previously only available on some System Overview pages (for example, the alf Cen page).

The Planetary Systems tables contain stellar parameters that correspond to planetary solutions, or planetary parameters published together as a set. But, many host stars, and their stellar companions, have stellar parameters determined separately from planetary solutions. Previously, these stellar solutions have only been available on the System Overview pages, so the new Stellar Hosts Table provides a consolidated view to these data. Note that the table does not yet include stellar parameters for stars hosting planetary candidates.

Stellar Hosts is similar to our other web-based, interactive tables, and includes our newest plotting feature for instant histogram and scatter plots (see our Jan. 18, 2024 news item for details). It's also supported by our Table Access Protocol (TAP) service. To set up a new query, consult our TAP User Guide and the table's data column definitions.

Once you've had a chance to try out the new table, let us know what you think!

Exoplanet Data by the Numbers

This week's release has some impressive numbers, specifically:

  1. 14: New planets!
  2. 449: Planets with updated ephemerides from ExoClock III!
  3. 165: New parameter sets for confirmed planets!
  4. 1: New JWST transmission spectrum for WASP-96 b!

The new planets are HD 134606 b, c, d, e, & f, TOI-238 b & c, TOI-1386 b & c, TOI-1751 b, Kepler-48 f, Kepler-100 e, and Kepler-139 d & e. Click on their names to go directly to their System Overview pages, or browse all system parameters in the archive (including this week's new sets) with the Planetary Systems and Planetary Systems Composite Data tables.

The new ephemerides, consisting of orbital periods and mid-transit times, have been integrated into our Planetary Systems tables, System Overview pages, and the Transit and Ephemeris Service.

To view and work with the new WASP-96 b spectrum, check out the Atmospheric Spectroscopy Table.

Two New Planets and Multi-spectra Plotting

We've updated the Atmospheric Spectroscopy Table to enable users to overplot multiple spectra. Users may now plot spectra of the same planet taken with multiple instruments at the same time, or compare spectra of different planets to identify key similarities or differences. Try it out and let us know what you think!

We've also added two new planets, both of which are TOI confirmations of super-Earths around M dwarf stars: Wolf-327 b and TOI-2266 b. The new planet parameters can be accessed from their System Overview pages, the Planetary Systems Table, and the Planetary Systems Composite Data Table.

Finally, we have added a new parameter set for HIP 75056 A b, which sets its mass to > 30 M_J and above our mass cut-off. HIP 75056 A b parameters can still be seen in its System Overview page, but it no longer appears in the Planetary Systems tables and now has a status of False Positive Planet.

Three New Planets and New Spectra for 12 Planets

This week, we've added spectra for 12 planets to the Atmospheric Spectroscopy Table, including new spectra taken by JWST for super-Earths GJ 367 b and GJ 1132 b. Both JWST spectra rule out the probability of the super-Earths having large, hydrogen-dominated atmospheres. The other new spectra are for the planets HAT-P-19 b, HAT-P-51 b, HAT-P-55 b, HAT-P-65 b, HAT-P-26 b, HAT-P-12 b, HD 209458 b, WASP-6 b, WASP-17 b, and WASP-39 b.

We have also added three new microlensing planets, KMT-2018-BLG-0885 b, KMT-2019-BLG-0297 b, and KMT-2019-BLG-0335 b. Access the new data in the system overview pages, the Planetary Systems Table, or the Planetary Systems Composite Data Table. Additional microlensing-specific parameters are also available in the Microlensing Planets Table.

Quicker and Easier Exoplanet Data Plots

We've made it even easier to make scatter plots and histograms with Planetary Systems data, with a new built-in and interactive feature that generates plots ready for publication, presentation, and data exploration.

To access the feature:

  1. Go to the Planetary Systems (PS) or Planetary Systems Composite Data (PSCompPars) table.
  2. Filter the table to display only the data you want to plot. (If needed, consult the Interactive Table User Guide's Sorting and Filtering Data section.)
  3. Click the Plot Table button and then select Histogram Plot or Scatter Plot from the drop-down list. The plot will open in a new browser tab.

For more information, see the ExoPlots User Guide.

This new feature is currently in Beta release, so there may be brief performance issues while we work on improvements and additional features. Please let us know how it works for you (or doesn't) and if you encounter any issues through our Helpdesk.

More TAP-supported Tables

As part of our continued adoption of the IVOA's Table Access Protocol (TAP) standard, we've migrated the following Kepler and K2 data sets from the archive's old API service to the newer TAP service:

  • K2 Targets: k2targets
  • Kepler Stellar, including distinct access for the following deliveries: keplerstellar, q1_q12_ks, q1_q16_ks, q1_q17_dr24_ks, q1_q17_dr25_ks, q1_q17_dr25_sup_ks
  • Kepler Time Series: keplertimeseries
  • Kepler Threshhold-Crossing Events, including distinct access for the following deliveries: q1_q12_tce, q1_q16_tce, q1_q17_dr24_tce, q1_q17_dr25_tce
  • Kepler Objects-of-Interest (KOI), including distinct access for the following deliveries: cumulative, q1_q6_koi, q1_q8_koi, q1_q12_koi, q1_q16_koi, q1_q17_dr24_koi, q1_q17_dr25_koi, q1_q17_dr25_sup_koi

The old API support for these tables will be discontinued in the near future, so please convert any existing API queries to TAP queries, and use TAP for all new queries (see documentation here).

Ringing in the New Year With Three Planets

Our first release for 2024 features HD 63433 d—the closest, young, Earth-sized planet discovered to date! According to the discovery paper, this planet is located ~22 parsecs from Earth and is the smallest confirmed planet with an age less than 500 Myr. Check out the archive's HD 63433 System Overview page and read the NASA media release for details.

Two additional planets added this week are OGLE-2019-BLG-1180L b and KMT-2021-BLG-1770L b. The planets have been added to the Planetary Systems Table and its companion table the Planetary Systems Composite Data Table, where you can view, filter, sort, and download data. Their data are also available in our Microlensing Planets table.
