Time-Domain Astrophysics with the Transiting Exoplanet Survey Satellite
The Transiting Exoplanet Survey Satellite (TESS) is conducting an all-sky survey with the primary aim of detecting planets orbiting nearby stars. However, its large field of view and 200 s imaging cadence are useful for other science cases, ranging from stellar astrophysics to transient science. …

CCD photometric precision for the Transiting Exoplanet Survey Satellite (TESS)
We seek to fully characterize all noise contributions along the CCD and electronics signal path specific to the equipment to be used on board the TESS all-sky space observatory. We adjust physical variables in such a way as to minimize this noise and achieve a photometric precision limited in large …
