High-Amplitude gamma Doradus Variables
Ernst Paunzen, Klaus Bernhard, Stefan Huemmerich +3
According to most literature sources, the amplitude of the pulsational variability observed in gamma Doradus stars does not exceed 0.1 mag in Johnson V. We have analyzed fifteen hi…
The ASAS-SN Catalog of Variable Stars VII: Contact Binaries are Different Above and Below the Kraft Break
T. Jayasinghe, K. Z. Stanek, C. S. Kochanek +11
We characterize W UMa type (EW) contact binaries, including new discoveries, using ASAS-SN -band all-sky light curves along with archival data fr…
The ASAS-SN Catalog of Variable Stars VI: An All-Sky Sample of Scuti Stars
T. Jayasinghe, K. Z. Stanek, C. S. Kochanek +10
We characterize an all-sky catalog of Scuti variables in ASAS-SN, which includes new discoveries. Using distances from \textit{Gaia} DR2, we deriv…
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 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…
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…
