The Rise and Fall of ASASSN-18pg: Following a TDE from Early To Late Times
Thomas W. -S. Holoien, Katie Auchettl, Michael A. Tucker +29
We present nearly 500 days of observations of the tidal disruption event ASASSN-18pg, spanning from 54 days before peak light to 441 days after peak light. Our dataset includes X-r…
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…
ASASSN-15pz: Revealing Significant Photometric Diversity among 2009dc-like, Peculiar SNe Ia
Ping Chen, Subo Dong, Boaz Katz +17
We report comprehensive multi-wavelength observations of a peculiar Type Ia-like supernova ("SN Ia-pec") ASASSN-15pz. ASASSN-15pz is a spectroscopic "twin" of SN 2009dc, a so-calle…
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…
ASASSN-18di: discovery of a flare on a mid-M dwarf
Romy Rodríguez, Sarah J. Schmidt, Tharindu Jayasinghe +9
We report and characterize a white-light superflare on a previously undiscovered M dwarf detected by the ASAS-SN survey. Employing various color-magnitude and color-spectral type r…
The Rise and Peak of the Luminous Type IIn SN 2017hcc/ATLAS17lsn from ASAS-SN and Swift UVOT Data
J. L. Prieto, Ping Chen, Subo Dong +7
We present observations of the rise and peak of the Type IIn supernova SN 2017hcc/ATLAS17lsn obtained by the All-Sky Automated Survey for Supernovae (ASAS-SN) and Swift UVOT. The l…
