Abstract (from CDS):

The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to routinely monitor the whole sky with a cadence of ∼2-3 d down to V <= 17 mag. ASAS-SN has monitored the whole sky since 2014, collecting ∼100-500 epochs of observations per field. The V-band light curves for candidate variables identified during the search for supernovae are classified using a random forest classifier and visually verified. We present a catalogue of 66 179 bright, new variable stars discovered during our search for supernovae, including 27 479 periodic variables and 38 700 irregular variables. V-band light curves for the ASAS-SN variables are available through the ASAS-SN variable stars data base(https://asas-sn.osu.edu/variables). The data base will begin to include the light curves of known variable stars in the near future along with the results for a systematic, all-sky variability survey.

Journal keyword(s): catalogues - surveys - binaries: eclipsing - stars: variables: general

VizieR on-line data: <CDS Catalogue: II/366>

Nomenclature: ASASSN-V JHHMMSS.ss+DDMMSS.s N=66179.

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: 170
