Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
A Potential Progenitor for the Type Ic Supernova 2017ein
Charles D. Kilpatrick, Tyler Takaro, Ryan J. Foley +9
We report the first detection of a credible progenitor system for a Type Ic supernova (SN Ic), SN 2017ein. We present spectra and photometry of the SN, finding it to be similar to…
SN 2017ens: The Metamorphosis of a Luminous Broad-lined Type Ic Supernova into an SN IIn
T. -W. Chen, C. Inserra, M. Fraser +46
We present observations of supernova (SN) 2017ens, discovered by the ATLAS survey and identified as a hot blue object through the GREAT program. The redshift z=0.1086 implies a pea…
The Dusty Progenitor Star of the Type II Supernova 2017eaw
Charles D. Kilpatrick, Ryan J. Foley
We present pre-explosion photometry of the likely progenitor star of the Type II supernova (SN II) 2017eaw in NGC 6946. We use a Hubble Space Telescope (HST) image of SN 2017eaw to…
