Record-breaking polarization from the interacting superluminous supernova 2017hcc
Jon C. Mauerhan, Nathan Smith, G. Grant Williams +12
We present multiepoch spectropolarimetry of the superluminous interacting Type IIn supernova SN2017hcc, covering 16 to 391 days after explosion. In our first epoch we measure conti…
V5856 Sagittarii/2016: Broad Multi-Epoch Spectral Coverage of a Sustained High Luminosity Nova
Robert Williams, Frederick M. Walter, Richard J. Rudy +4
Nova V5856 Sagittarii is unique for having remained more than nine magnitudes above its pre-outburst brightness for more than six years. Extensive visible and IR spectra from the t…
Discovery of a 310-day Period from the Enshrouded Massive System NaSt1 (WR 122)
Ryan M. Lau, Samaporn Tinyanont, Matthew J. Hankins +15
We present optical and infrared (IR) light curves of NaSt1, also known as Wolf-Rayet (WR) 122, with observations from Palomar Gattini-IR (PGIR), the Zwicky Transient Facility (ZTF)…
Berkeley Supernova Ia Program: Data Release of 637 Spectra from 247 Type Ia Supernovae
Benjamin E. Stahl, WeiKang Zheng, Thomas de Jaeger +18
We present 637 low-redshift optical spectra collected by the Berkeley Supernova Ia Program (BSNIP) between 2009 and 2018, almost entirely with the Kast double spectrograph on the S…
The Berkeley Sample of Stripped-Envelope Supernovae
Isaac Shivvers, Alexei V. Filippenko, Jeffrey M. Silverman +22
We present the complete sample of stripped-envelope supernova (SN) spectra observed by the Lick Observatory Supernova Search (LOSS) collaboration over the last three decades: 888 s…
Stripped-envelope supernova SN 2004dk is now interacting with hydrogen-rich circumstellar material
Jon C. Mauerhan, Alexei V. Filippenko, Weikang Zheng +4
The dominant mechanism and time scales over which stripped-envelope supernovae (SNe) progenitor stars shed their hydrogen envelopes are uncertain. Observations of Type Ib and Ic SN…
