LSQ13ddu: A rapidly-evolving stripped-envelope supernova with early circumstellar interaction signatures
Peter Clark, Kate Maguire, Cosimo Inserra +30
This paper describes the rapidly evolving and unusual supernova LSQ13ddu, discovered by the La Silla-QUEST survey. LSQ13ddu displayed a rapid rise of just 4.80.9 d to reach a…
The Carnegie Supernova Project II. Early observations and progenitor constraints of the Type Ib supernova LSQ13abf
M. D. Stritzinger, F. Taddia, S. Holmbo +19
Supernova LSQ13abf was discovered soon after explosion by the La Silla-QUEST Survey and followed by the CSP II at optical and near-IR wavelengths. Our analysis indicates LSQ13abf w…
Carnegie Supernova Project-II: Near-infrared Spectroscopic Diversity of Type II Supernovae
S. Davis, E. Y. Hsiao, C. Ashall +24
We present near-infrared (NIR) spectra of Type II supernovae (SNe II) from the Carnegie Supernova Project-II (CSP-II), the largest such dataset published to date. We iden…
Luminous Type II supernovae for their low expansion velocities
Ó. Rodríguez, G. Pignata, J. P. Anderson +27
We present optical and near-IR data of three Type II supernovae (SNe II), SN 2008bm, SN 2009aj, and SN 2009au. These SNe display the following common characteristics: signs of earl…
SN 2016gsd: An unusually luminous and linear type II supernova with high velocities
T. M. Reynolds, M. Fraser, S. Mattila +27
We present observations of the unusually luminous Type II supernova (SN) 2016gsd. With a peak absolute magnitude of V = 19.95 0.08, this object is one of the brightest Typ…
Comparison of the optical light curves of hydrogen-rich and hydrogen-poor type II supernovae
P. J. Pessi, G. Folatelli, J. P. Anderson +12
Type II supernovae (SNe II) show strong hydrogen features in their spectra throughout their whole evolution while type IIb supernovae (SNe IIb) spectra evolve from dominant hydroge…
A Physical Basis for the H-band Blue-edge Velocity and Light-Curve Shape Correlation in Context of Type Ia Supernova Explosion Physics
C. Ashall, P. Hoeflich, E. Y. Hsiao +17
Our recent work demonstrates a correlation between the high-velocity blue edge, , of the iron-peak Fe/Co/Ni -band emission feature and the optical light curve shape of…
SN 2016coi (ASASSN-16fp): an energetic H-stripped core-collapse supernova from a massive stellar progenitor with large mass loss
G. Terreran, R. Margutti, D. Bersier +25
We present comprehensive observations and analysis of the energetic H-stripped SN 2016coi (a.k.a. ASASSN-16fp), spanning the -ray through optical and radio wavelengths, acquired…
The Most Rapidly Declining Type I Supernova 2019bkc/ATLAS19dqr
Ping Chen, Subo Dong, M. D. Stritzinger +21
We report observations of the hydrogen-deficient supernova (SN) 2019bkc/ATLAS19dqr. With B- and r-band decline between peak and 10 days post peak of Delta m_10(B)=5.24+/-0.07 mag a…
Carnegie Supernova Project-II: Using Near-Infrared Spectroscopy to determine the location of the outer Ni in Type Ia Supernovae
C. Ashall, E. Y. Hsiao, P. Hoeflich +17
We present the -band wavelength region of thirty post-maximum light near-infrared (NIR) spectra of fourteen transitional and sub-luminous type Ia supernovae (SNe Ia), extending…
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…
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…
Nebular Spectra of 111 Type Ia Supernovae Disfavor Single Degenerate Progenitors
M. A. Tucker, B. J. Shappee, P. J. Vallely +15
We place statistical constraints on Type Ia supernova (SN Ia) progenitors using 227 nebular phase spectra of 111 SNe Ia. We find no evidence of stripped companion emission in any o…
Constraining Type Iax Supernova Progenitor Systems with Stellar Population Aging
Tyler Takaro, Ryan J. Foley, Curtis McCully +6
Type Iax supernovae (SNe~Iax) are the most common class of peculiar SNe. While they are thought to be thermonuclear white-dwarf (WD) SNe, SNe~Iax are observationally similar to, bu…
