The ASAS-SN Catalog of Variable Stars V: Variables in the Southern Hemisphere
T. Jayasinghe, K. Z. Stanek, C. S. Kochanek +13
The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline ( yrs) light curves for sources brighter than V mag across the whole sky. As part…
The ASAS-SN Catalog of Variable Stars IV: Periodic Variables in the APOGEE Survey
Michal Pawlak, O. Pejcha, P. Jakubcik +12
We explore the synergy between photometric and spectroscopic surveys by searching for periodic variable stars among the targets observed by the Apache Point Observatory Galactic Ev…
The ASAS-SN Catalog of Variable Stars III: Variables in the Southern TESS Continuous Viewing Zone
T. Jayasinghe, K. Z. Stanek, C. S. Kochanek +13
The All-Sky Automated Survey for Supernovae (ASAS-SN) provides long baseline ( yrs) light curves for sources brighter than V mag across the whole sky. The Tran…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
The ASAS-SN Catalog of Variable Stars II: Uniform Classification of 412,000 Known Variables
T. Jayasinghe, K. Z. Stanek, C. S. Kochanek +12
The variable stars in the VSX catalog are derived from a multitude of inhomogeneous data sources and classification tools. This inhomogeneity complicates our understanding of varia…
An All-Sky Search For R Coronae Borealis Stars in ASAS-SN
J. V. Shields, T. Jayasinghe, K. Z. Stanek +6
We report the discovery of 19 new R Coronae Borealis (RCB) star and DY Per candidates with light curves from the All-Sky Automated Survey for Supernovae (ASAS-SN). We examined both…
