Abstract (from CDS):

The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long-baseline (∼4 yr) light curves for sources brighter than V <= 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 ∼1.3 million V-band light curves covering a total of ∼1000 deg^2 towards the southern TESS CVZ and have systematically searched these sources for variability. We have identified ∼11 700 variables, including ∼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 ∼1.3 million sources studied in this work. This effort will be extended to provide ASAS-SN light curves for ∼50 million sources over the entire sky.

Status at CDS : All or part of tables of objects could be ingested in SIMBAD; there are some issues with cross-identifications or classifications.

CDS comments: The resolution of this survey is 15''. As a consequence the astrometry is poor, usually within 5'', but it can be more than 1 pixel. Thus the identifications in astrometric catalogues and the ingestion in Simbad are quite challenging.

Simbad objects: 814
