The ASAS-SN catalogue of variable stars III: variables in the southern TESS continuous viewing zone

Original language description

The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long-baseline (similar to 4 yr) light curves for sources brighter than V less than or similar to 17 mag across the whole sky. The Transiting Exoplanet Survey Satellite (TESS) has started to produce high-quality light curves with a baseline of at least 27 d, eventually for most of the sky. The combination of ASAS-SN and TESS light curves probes both long-and short-term variability in great detail, especially towards the TESS continuous viewing zones (CVZ) at the ecliptic poles. We have produced similar to 1.3 million V-band light curves covering a total of similar to 1000 deg(2) towards the southern TESS CVZ and have systematically searched these sources for variability. We have identified similar to 11 700 variables, including similar to 7 000 new discoveries. The light curves and characteristics of the variables are all available through the ASAS-SN variable stars data base (https://asas-sn.osu.edu/variables). We also introduce an online resource to obtain pre-computed ASAS-SN V-band light curves (https://asas-sn.osu.edu/photometry) starting with the light curves of the similar to 1.3 million sources studied in this work. This effort will be extended to provide ASAS-SN light curves for similar to 50 million sources over the entire sky.
