<p align="center">The shape and periodic nature of a star’s light
curve can uncover important information about its intrinsic
properties, including information about its magnetic activity,
rotation, and potential stellar or planetary companions.
Understanding stellar variability is especially critical for
accurately constraining exoplanet properties and understanding how
stars may affect planetary evolution. Stellar variability can also
hide the presence of small exoplanets, such that constraining
variability and finding exoplanets around variable stars is
important for gaining a complete picture of exoplanet
demographics. In order to understand the variability of stars
across the sky, we developed the TESS Stellar Variability Catalog
(TESS-SVC). The TESS-SVC contains ~84,000 stars that have been
identified as being periodically variable (rotation, pulsation,
eclipsing binaries, etc.) and has thus far been used for exoplanet
confirmation, characterizing exoplanet host stars, and
characterizing stellar activity and other types of variability. I
will also discuss how we use the TESS-SVC to search for stellar
activity cycles, investigate how exoplanets are impacted by active
stars, and understand how variable stars may influence their
Galactic environments.</p>
