The disappearances of six supernova progenitors
Schuyler D. Van Dyk, Asia de Graw, Raphael Baer-Way +8
As part of a larger completed Hubble Space Telescope (HST) Snapshot program, we observed the sites of six nearby core-collapse supernovae (SNe) at high spatial resolution: SN 2012A…
SN 2022oqm -- a Ca-rich explosion of a compact progenitor embedded in C/O circumstellar material
I. Irani, Ping Chen, Jonathan Morag +27
We present the discovery and analysis of SN\,2022oqm, a Type Ic supernova (SN) detected \,day after explosion. The SN rises to a blue and short-lived (2\,days) initial peak. Ea…
Spectropolarimetry of the Thermonuclear Supernova 2021rhu: High Calcium Polarization 79 Days After Peak Luminosity
Yi Yang, Huirong Yan, Lifan Wang +19
We report spectropolarimetric observations of the Type Ia supernova (SN) 2021rhu at four epochs: 7, +0, +36, and +79 days relative to its -band maximum luminosity. A waveleng…
Spectropolarimetry of the tidal disruption event AT 2019qiz: a quasispherical reprocessing layer
Kishore C. Patra, Wenbin Lu, Thomas G. Brink +3
We present optical spectropolarimetry of the tidal disruption event (TDE) AT 2019qiz on days and relative to maximum brightness. Continuum polarization, which informs th…
Early-Time Ultraviolet Spectroscopy and Optical Follow-up Observations of the Type IIP Supernova 2021yja
Sergiy S. Vasylyev, Alexei V. Filippenko, Christian Vogl +19
We present three epochs of early-time ultraviolet (UV) and optical HST/STIS spectroscopy of the young, nearby Type IIP supernova (SN) 2021yja. We complement the HST data with two e…
