High-Cadence, Early-Time Observations of Core-Collapse Supernovae From the TESS Prime Mission
P. J. Vallely, C. S. Kochanek, K. Z. Stanek +2
We present observations from the Transiting Exoplanet Survey Satellite (TESS) of twenty bright core-collapse supernovae with peak TESS-band magnitudes mag. We reduce t…
ASASSN-14ko is a Periodic Nuclear Transient in ESO 253-G003
Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle +24
We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated Survey for S…
SN2019yvq Does Not Conform to SN Ia Explosion Models
M. A. Tucker, C. Ashall, B. J. Shappee +7
We present new photometric and spectroscopic observations of SN 2019yvq, a Type Ia supernova (SN Ia) exhibiting several peculiar properties including an excess of UV/optical flux w…
Discovery and Follow-up of ASASSN-19dj: An X-ray and UV Luminous TDE in an Extreme Post-Starburst Galaxy
Jason T. Hinkle, T. W. -S. Holoien, K. Auchettl +28
We present observations of ASASSN-19dj, a nearby tidal disruption event (TDE) discovered in the post-starburst galaxy KUG 0810+227 by the All-Sky Automated Survey for Supernovae (A…
The ASAS-SN Catalog of Variable Stars VIII: "Dipper" Stars in the Lupus Star-Forming Region
J. W. Bredall, B. J. Shappee, E. Gaidos +9
Some young stellar objects such as T Tauri-like "dipper" stars vary due to transient partial occultation by circumstellar dust, and observations of this phenomenon inform us of con…
Direct evidence for shock-powered optical emission in a nova
Elias Aydi, Kirill V. Sokolovsky, Laura Chomiuk +39
Classical novae are thermonuclear explosions that occur on the surfaces of white dwarf stars in interacting binary systems (Bode & Evans 2008). It has long been thought that the lu…
