A Carbon/Oxygen-dominated Atmosphere Days After Explosion for the "Super-Chandrasekhar" Type Ia SN 2020esm
Georgios Dimitriadis, Ryan J. Foley, Nikki Arendse +18
Seeing pristine material from the donor star in a Type Ia supernova (SN Ia) explosion can reveal the nature of the binary system. In this paper, we present photometric and spectros…
On the Progenitor of the Type IIb Supernova 2016gkg
Charles D. Kilpatrick, Ryan J. Foley, Louis E. Abramson +7
We present a detection in pre-explosion Hubble Space Telescope (HST) imaging of a point source consistent with being the progenitor star of the Type IIb supernova (SN IIb) 2016gkg.…
Optical and ultraviolet spectroscopic analysis of SN 2011fe at late times
Brian Friesen, E. Baron, Jerod T. Parrent +16
We present optical spectra of the nearby Type Ia supernova SN 2011fe at 100, 205, 311, 349, and 578 days post-maximum light, as well as an ultraviolet spectrum obtained with Hubble…
Type Ia Supernova Spectral Features in the Context of Their Host Galaxy Properties
Y. -C. Pan, M. Sullivan, K. Maguire +5
We analyse spectroscopic measurements of 122 type Ia supernovae (SNe Ia) with z<0.09 discovered by the Palomar Transient Factory, focusing on the properties of the Si II 6355 and C…
Exploring the spectral diversity of low-redshift Type Ia supernovae using the Palomar Transient Factory
Kate Maguire, Mark Sullivan, Yen-Chen Pan +15
We present an investigation of the optical spectra of 264 low-redshift (z < 0.2) Type Ia supernovae (SNe Ia) discovered by the Palomar Transient Factory, an untargeted transient su…
A Continuum of H- to He-Rich Tidal Disruption Candidates With a Preference for E+A Galaxies
Iair Arcavi, Avishay Gal-Yam, Mark Sullivan +23
We present the results of a Palomar Transient Factory (PTF) archival search for blue transients which lie in the magnitude range between "normal" core-collapse and superluminous su…
