A Giant Planet Orbiting a Tiny Star
One of this week's four planets is TOI-6894 b, a sub-Saturn-mass planet orbiting a low-mass red dwarf—the smallest known star to host a transiting giant planet. This discovery challenges some current planetary formation models and theories. Check out the University College London media release and the discovery paper.
The other new planets are TOI-2969 b, TOI-2989 b, and TOI-5300 b. There are also new parameters for seven planets: KELT-11 b, Kepler-10 b, c, & d, MASCARA-4 b, and TOI-1468 b, WASP-127 b. Click on a planet name to go directly to its System Overview page, or browse the Planetary Systems and Planetary Systems Composite Data tables.
We also have seven more spectra for five planets: GJ 357 b, HAT-P-2 b, LHS 1140 c, LTT 1445 A b, and WASP-127 b. You can find these in the Atmospheric Spectroscopy Table.An ExoFOP Milestone: 1 Million Files and Counting!
The Exoplanet Follow-up Observing Program (ExoFOP), which was created in 2008 to help researchers collaborate and share observational data to confirm exoplanet candidates, has surpassed one million user-submitted data files.
This incredible achievement is a testament to the dedication and collaboration of the exoplanet research community. Of the nearly 6,000 exoplanets confirmed thus far, data shared by the community through ExoFOP has contributed to approximately 4,000 of them.
From all of us at NExScI, thank you for your continued support and commitment to exoplanet science. This milestone would not have been possible without you. Here's to the next million!

Say Ciao to ROME, Our Newest Dataset
This week the NASA Exoplanet Archive has released the Robotic Observations of Microlensing Events/Reactive Event Assessment (ROME/REA) dataset, published last year in Street et al. (2024).
The data release consists of ~8 million light curves in three optical passbands from 20 fields in the Galactic bulge over a three-year period, down to a limiting magnitude of i~18th magnitude. The data have a typical cadence of 10-15 hours while the fields were visible to the Las Cumbres Observatory network of telescopes. The data contain thousands of microlensing events, eclipsing binaries, and RR Lyrae and longer-period variable stars, and can be used as a training set for classification of objects in future surveys, such as the Vera Rubin Legacy Survey of Space and Time, starting this year.
The ROME/REA data are served through the archive through our interactive Firely-based service. To get started, click the Data pull-down menu in our site navigation and select ROME/REA Microlensing Survey in the Other section. (Here is the direct link.)
More information about the ROME/REA dataset and using the online service is provided on the User Guide tab within the interface:
Four New Planets and Six Direct Imaging Spectra
Also released this week are planets Kepler-139 f, TOI-3493 b, TOI-6478 b, and 2M1510 b, as well as more parameters for GPX-1 b and HD 3167 b & c. Click on their names to view their System Overview page, or browse Planetary Systems and Planetary Systems Composite Data tables.

A Planet Disintegrating Around Its Bright Host Star
One of this week's five planets is orbiting its star so closely that it's disintegrating in the intense heat. BD+05 4868 A b's demise is expected to happen over the next two million years, and because the host is a bright TESS star, researchers have an opportunity to observe the end of the planet's life. Check out this Astrobites article and the discovery paper for details.
The other new planets are TOI-1266 d, LP 261-75 b, ZTF J1230-2655 b, and ZTF J1828+2308 b. We've also added new parameters for TOI-640 b, TOI-677 b, and GJ 436 b.

Real and Synthetic Exoplanet Data
This week's release contains data for six real planets, and over 3 million spectra for simulated rocky planets.
Frontier Development Lab INARA Dataset
One of the teams from the 2018 FDL Astrobiology challenge has published a paper on their set of over 3 million synthetic rocky planet spectra, all of which are available on the Exoplanet Archive.
The spectra are modeled after initial Habitable Worlds Observatory-like design criteria, and provide a training set for machine-learning algorithms to efficiently perform atmospheric retrievals on real-life spectral data. The dataset joins the PyATMOS dataset, a grid of model atmospheres produced by a second team from the same FDL challenge.
Access the INARA data by selecting Frontier Development Lab Datasets from our website's Data pull-down menu, or use this direct link.
Six New Planets
This week's six new planets feature a super-Earth and a sub-Neptune found orbiting TOI-1453—a planetary system found 250 light-years away in the Draco constellation. Planet c is one of the least-dense sub-Neptunes ever discovered. Read the Star Institute media release and the discovery paper for details.
The other new planets are GJ 1289 b, TOI-4364 b, TOI-5143 c, and TOI-7041 b. There are also new parameters for Qatar-6 b and KELT-10 b. Click on their names to go directly to their System Overview page, or browse the Planetary Systems and Planetary Systems Composite Data tables.

Thank You, Radial Velocity!
This week's release was made possible by the radial velocity technique: multiple TOIs were confirmed with radial velocity follow-up. One noteworthy planet from that batch is TOI-2537 b because it partially orbits in its star's habitable zone. Also, Jovian GJ 2126 b—which has a very eccentric orbit around an M0 star—is an RV-only discovery.
Learn more about the TOI confirmations in Tala Pinto et al. and Heidari et al.; details on GJ 2126 b are described in a separate paper.
The other new planets are: TOI-2295 b & c, TOI-2328 b, TOI-2537 c, TOI-3837 b, TOI-5027 b, TOI-5110 b, and TOI-6628 b.
