Traces of Helium Detected in Type Ic Supernova 2014L
Jing Lu, Wolfgang E. Kerzendorf, John T. O'Brien +6
The absence of helium features in optical spectra is one of the classification criteria for Type Ic supernovae (SNe Ic). However, it is highly debated whether helium is truly absen…

Physics-driven Explosions of Stripped High-Mass Stars: Synthetic Light Curves and Spectra of Stripped-Envelope Supernovae with Broad Lightcurves
Jing Lu, Brandon L. Barker, Jared Goldberg +5
Stripped-envelope supernovae (SESNe) represent a significant fraction of core-collapse supernovae, arising from massive stars that have shed their hydrogen and, in some cases, heli…
