The ASAS-SN catalogue of variable stars - V. Variables in the Southern hemisphere

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. As part of our effort to characterize the variability of all the stellar sources visible in ASAS-SN, we have produced similar to 30.1 million V-band light curves for sources in the Southern hemisphere using the APASS DR9 (AAVSO Photometric All-Sky Survey Data Release) catalogue as our input source list. We have systematically searched these sources for variability using a pipeline based on random forest classifiers. We have identified similar to 220 000 variables, including similar to 88 300 new discoveries. In particular, we have discovered similar to 48 000 red pulsating variables, similar to 23 000 eclipsing binaries, similar to 2200 delta-Scuti variables, and similar to 10 200 rotational variables. 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). The pre-computed ASAS-SN V-band light curves for all the similar to 30.1 million sources are available through the ASAS-SN photometry data base (https://asas-sn.osu.edu/photometry). This effort will be extended to provide ASAS-SN light curves for sources in the Northern hemisphere and for V less than or similar to 17 mag sources across the whole sky that are not included in APASS DR9.
