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…
The shape of SN 1993J re-analyzed
H. F. Stevance, D. Baade, J. R. Bruten +8
SN 1993J is one of the best studied Type IIb supernovae. Spectropolarimetric data analyses were published over two decades ago at a time when the field of supernova spectropolarime…
The New EXor Outburst of ESO-H-alpha~99 observed by Gaia ATLAS and TESS
Klaus W. Hodapp, Bo Reipurth, Bertil Pettersson +11
We report photometry and spectroscopy of the outburst of the young stellar object ESO-Halpha 99. The outburst was first noticed in Gaia alert Gaia18dvc and later by ATLAS. We have…
Discovery and Early Evolution of ASASSN-19bt, the First TDE Detected by TESS
Thomas W. -S. Holoien, Patrick J. Vallely, Katie Auchettl +22
We present the discovery and early evolution of ASASSN-19bt, a tidal disruption event (TDE) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) at a distance of $d\…
ASASSN-18tb: A Most Unusual Type Ia Supernova Observed by TESS and SALT
P. J. Vallely, M. Fausnaugh, S. W. Jha +16
We present photometric and spectroscopic observations of the unusual Type Ia supernova ASASSN-18tb, including a series of SALT spectra obtained over the course of nearly six months…
