Detection of Circumstellar Helium in Type Iax Progenitor Systems
Wynn Jacobson-Galan, Ryan Foley, Josiah Schwab +6
We present direct spectroscopic modeling of 44 Type Iax supernovae (SNe Iax) using spectral synthesis code SYNAPPS. We confirm detections of helium emission in the early-time spect…
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…
Constraining Type Ia Supernova Progenitor Scenarios with Extremely Late-time Photometry of Supernova SN 2013aa
Wynn V. Jacobson-Galan, Georgios Dimitriadis, Ryan J. Foley +1
We present Hubble Space Telescope observations and photometric measurements of the Type Ia supernova (SN Ia) SN 2013aa 1500 days after explosion. At this epoch, the luminosity is p…
