Accepted Identifiers and Catalogs
If the user enters the name of star that has been identified by the Exoplanet Archive as being part of a multiple system, the user will be given the choice to select between either component of the system. For example, if a user enters 83 Leo, the Exoplanet Archive returns the list of stellar components (83 Leo A, 83 Leo B) and asks the user to chose the appropriate stellar component.
If a user enters a name that is not recognized by the Exoplanet Archive, it is possible that the user has used an alias
which is unknown to the Exoplanet Archive but is known to SIMBAD. The user input is passed to SIMBAD and NED to
search for additional aliases which may be recognized by the Exoplanet Archive.
If no SIMBAD or NED alias is found, the user is notified that the input is not recognized by the Exoplanet Archive, SIMBAD or NED.
If the input is recognized by SIMBAD, the user is given a list of SIMBAD aliases. The alias list is matched
against the Exoplanet Archive alias list to search for an Exoplanet Archive entry. The full SIMBAD-Exoplanet Archive matching is displayed to
allow the user to determine if the correct star has been identified. If multiple Exoplanet Archive sources are associated
with a given SIMBAD alias, the multiple matches are also shown. The Exoplanet Archive object column provides a direct link
to all matched entries in the Exoplanet Archive.
For example, HD 41004 is in the Exoplanet Archive, but the alias GSC 08092-00538 is not recognized by the Exoplanet Archive. Entering
GSC 08092-00538 into the Exoplanet Archive triggers a query to SIMBAD for a list of additional aliases. The aliases are
matched to aliases recognized by the Exoplanet Archive. In the case of HD 41004, there is an A and B component which is
also indicated in the matched results. If the input is recognized by SIMBAD, a direct link to the SIMBAD
entry is provided.
If the alias is recognized by SIMBAD but is classified as a non-Galactic object, a link to the NED entry is also provided. (example: M 31).

In the instructions above
- N = an integer digit (0-9).
- HH = an integer number of hours (00-23).
- MM = an integer number of minutes (00-59).
- m = fraction of a minute (0-9), e.g., MMm = 217 corresponds to 21.7 minutes.
- SSSS or SSS = seconds plus fraction of second (0000-5999 or 000-599), e.g., SSSS = 2248 corresponds to 22.48 seconds.
- DD = integer number of degrees (00-89).
- YYYY = integer number of years (2000-2099).
- A = a letter of the (English) alphabet (A-Z or a-z).
- ggg = The full Greek letter (e.g., alpha, beta) or the 3 English letter abbreviation of Greek letters (e.g., alf, bet). For the Greek letters mu and nu, please repeat the last character (muu, nuu) to enforce a three character abbreviation.
- s = "+" or "-" sign.
- CON = Three letter abbreviation of constellation name (e.g., TAU, AND).
All other letters are entered as is. Note also that
- Italicized = an instruction
- Anything written in [square brackets] may or may not be part of a query.
- Leading zeros (0s) may be omitted
- The Exoplanet Archive is not case-sensitive
Notes
Regarding Durchmusterung catalogs: The Exoplanet Archive uses the same designations as published in the original Durchmusterung catalogs. That is, the identifiers BD, CD, CPD, SD are not interchangeable. In the same spirit, the Exoplanet Archive also does not recognize the generic Durchmusterung (DM) identifier
