Welcome to ExoFOP-TESS

The Exoplanet Follow-up Observing Program for TESS (ExoFOP-TESS) website is designed to optimize resources and facilitate collaboration in follow-up studies of targets observed by TESS, an Explorer-class mission led by MIT. ExoFOP-TESS contains stellar parameters from the TESS Input Catalog (TIC), which is served by the Mikulski Archive for Space Telescopes (MAST), and planet parameters from the NASA Exoplanet Archive.

For information about participating in the TESS Guest Investigator program, please see the TESS Science Support Center.

ExoFOP Data Migration
The ExoFOP Archive is in the process of migrating to a single portal. The user uploaded content in the Kepler and K2 portals is being incorporated into the TESS portal. The original user and date of the upload will be retained. As content is migrated, the update feature for that parameter class in the original portal will be disabled. See Status.
