Abstract:
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.
Description:
This catalogue was compiled using observations taken by the "Brutus"
(Haleakala, Hawaii) and "Cassius" (CTIO, Chile) quadruple telescopes
between 2013 and 2018 with 200-600 epochs of observation for each
field to a depth of V< 17mag. The field of view of a single ASAS-SN
camera is 4.5deg^2^, the pixel scale is 8.0", and the full width at
half-maximum (FWHM) is 2pixels. The ASAS-SN cameras capture three 90s
images for every epoch which are merged to improve the signal-to-noise
ratio (S/N). ASAS-SN saturates at 10-11mag depending on the camera
and image position (Kochanek+ 2017PASP..129j4502K).
Starting in 2017, ASAS-SN expanded to five units with 20 telescopes.
The ASAS-SN telescopes are hosted by the Las Cumbres Observatory (LCO)
in Hawaii, Chile, Texas, and South Africa.
