The ASAS-SN catalogue of variable stars I: The Serendipitous Survey
Tharindu Jayasinghe,Christopher S. Kochanek,Krzysztof Z. Stanek,Benjamin J. Shappee,T W-S Holoien,Toda A Thompson,J. L. Prieto,J. L. Prieto,Subo Dong,M. Pawlak,J. V. Shields,G. Pojmanski,S. Otero,C. A. Britt,D. Will +14 more
TL;DR: The All Sky Automated Survey for Supernovae (ASASAS-SN) is the first optical survey to routinely monitor the whole sky with a cadence of 2-3 days down to V$\lesssim17$ mag as discussed by the authors.
Journal ArticleDOI

Todd A. Thompson,Todd A. Thompson,Christopher S. Kochanek,Krzysztof Z. Stanek,Carles Badenes,Carles Badenes,R. S. Post,Tharindu Jayasinghe,David W. Latham,Allyson Bieryla,Gilbert A. Esquerdo,Perry Berlind,Michael L. Calkins,Jamie Tayar,Jamie Tayar,Lennart Lindegren,Jennifer A. Johnson,Thomas W.-S. Holoien,Katie Auchettl,Katie Auchettl,Kevin R. Covey +20 more
TL;DR: For example, noninteracting binary systems with companion stars are typically found via their x-ray emission, generated by interaction and accretion as mentioned in this paper, and are expected to be plentiful in the Gala...
Journal ArticleDOI
The ASAS-SN catalogue of variable stars - II. Uniform classification of 412 000 known variables
Tharindu Jayasinghe,Krzysztof Z. Stanek,Christopher S. Kochanek,Benjamin J. Shappee,T W-S Holoien,Todd A. Thompson,J. L. Prieto,J. L. Prieto,Subo Dong,M. Pawlak,Ondřej Pejcha,J. V. Shields,G. Pojmanski,S. Otero,C. A. Britt,D. Will +15 more
TL;DR: In this paper, the authors homogeneously analyzed the ASAS-SN V-band light curves of the variable stars in the VSX catalog and classified them using an updated random forest classifier with an accuracy of 99.4%.
Journal ArticleDOI
Discovery of a Candidate Black Hole - Giant Star Binary System in the Galactic Field
Todd A. Thompson,Christopher S. Kochanek,Krzysztof Z. Stanek,Carles Badenes,R. S. Post,Tharindu Jayasinghe,David W. Latham,Allyson Bieryla,Gilbert A. Esquerdo,Perry Berlind,Michael L. Calkins,Jamie Tayar,Lennart Lindegren,Jennifer A. Johnson,Thomas W.-S. Holoien,Katie Auchettl,Kevin R. Covey +16 more
TL;DR: In this article, the authors reported the discovery of the first likely black hole in a non-interacting binary system with a field red giant by combining radial velocity measurements from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) with photometric variability data from the All-Sky Automated Survey for Supernovae (ASAS-SN).
Journal ArticleDOI
The ASAS-SN catalogue of variable stars III: variables in the southern TESS continuous viewing zone
Tharindu Jayasinghe,Krzysztof Z. Stanek,Christopher S. Kochanek,Benjamin J. Shappee,Thomas W.-S. Holoien,Todd A. Thompson,Todd A. Thompson,J. L. Prieto,J. L. Prieto,Subo Dong,M. Pawlak,Ondřej Pejcha,J. V. Shields,G. Pojmanski,S. Otero,N. Hurst,C. A. Britt,D. Will +17 more
TL;DR: 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.
