ASAS-SN catalog of variable stars

The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to routinely monitor the whole sky with a cadence of ~2-3d down to V<~17mag. 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. In Paper I (Jayasinghe+ 2018MNRAS.477.3145J), we present a catalogue of 66179 bright, new variable stars discovered during our search for supernovae, including 27479 periodic variables and 38700 irregular variables. In paper II (Jayasinghe+ 2019MNRAS.486.1907J), We extracted the ASAS-SN light curves of ~412000 variable stars previously discovered by other surveys and in the VSX catalogue. In paper III (Jayasinghe+ 2019MNRAS.485..961J), we extracted the ASAS-SN light curves of ~1.3 million sources within 18deg of the Southern Ecliptic Pole. These sources are within the southern TESS CVZ and will have well-sampled TESS light curves. In Paper IV (Pawlak+ 2019MNRAS.487.5932P), we have also explored the synergy between ASAS-SN and large-scale spectroscopic surveys using data from apogee. In Paper V (Jayasinghe+ 2020MNRAS.491...13J), we identified ~220000 variable sources with V<17mag in the southern hemisphere, of which ~88300 were new discoveries. In Paper VI (Jayasinghe+ 2020MNRAS.493.4186J), we derived period-luminosity relationships for {delta} Scuti stars. In Paper VII (Jayasinghe+ 2020MNRAS.493.4045J), we studied contact binaries. In Paper VIII (Bredall+ 2020, J/MNRAS/496/3257), we identified 11 new "dipper" stars in the Lupus star-forming region. In Paper IX (Jayasinghe+ 2021MNRAS.503..200J), we used spectroscopic information from LAMOST, GALAH, RAVE, and apogee to study the physical and chemical properties of these variables. In Paper X (Christy+ 2023MNRAS.519.5271C), we present the first all-sky catalogue of variables detected in the newer, deeper, higher cadence g-band ASAS-SN data.
