Variability Catalog of Stars Observed during the TESS Prime Mission
The Astrophysical Journal Supplement Series, 2023 During its 2 yr Prime Mission, TESS observed over 232,000 stars at a 2 minute cadence across ∼70% of the sky. These data provide a record of photometric variability across a range of astrophysically interesting timescales, probing stellar rotation ...

The ASAS-SN Catalog of Variable Stars X: Discovery of 116,000 New Variable Stars Using g-band Photometry [PDF]
Monthly notices of the Royal Astronomical Society, 2022 The All-Sky Automated Survey for Supernovae (ASAS-SN) is the first optical survey to monitor the entire sky, currently with a cadence of ≲ 24 hours down to g ≲ 18.5 mag. ASAS-SN has routinely operated since 2013, collecting ∼ 2,000 to over 7,500 epochs

Variability of Luminous Stars in the Large Magellanic Cloud Using 10 Years of ASAS Data [PDF]
, 2010 Motivated by the detection of a recent outburst of the massive luminous blue variable LMC-R71, which reached an absolute magnitude M_V = -9.3 mag, we undertook a systematic study of the optical variability of 1268 massive stars in the Large Magellanic ...

Database of Molecular Masers and Variable Stars [PDF]
, 2018 We present the database of maser sources in H2O, OH and SiO lines that can be used to identify and study variable stars at evolved stages. Detecting the maser emission in H2O, OH and SiO molecules toward infrared-excess objects is one of the methods of ...
