TEQUILA catalog of TESS images variables
Listed in IVOA Registry (Virtual Observatory)
Stellar variability and transient events provide critical insights into many areas of astrophysics.
Description
Progress in these fields has been accelerated by high-precision space-based photometry missions such as CoRoT, Kepler, and K2. NASA's ongoing Transiting Exoplanet Survey Satellite (TESS) represents another significant milestone, offering a unique combination of long observational baseline, high cadence, and nearly all-sky coverage.
However, extracting high-quality light curves from TESS full-frame images (FFIs) remains challenging due to contamination from scattered light and blending in crowded fields. In this study, we processed TESS FFIs to produce a comprehensive catalog of light curves for variable point sources observed during the satellite's prime mission. The resulting database, TESS Quick-look and Light curve Analysis (TEQUILA), provides over six million light curves.

These include stellar variables, transient events, instrumental systematics, and moving objects. The data were obtained using a pipeline based on difference image analysis, construction of high S/N reference frames, and fixed-radius aperture photometry. A convolutional neural network was used to flag systematic noise, and cross-matching with known Solar System objects was performed to identify contamination.
All extracted light curves are publicly accessible as a high-level science product through the MAST archive.
