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…
Effect of positronium on the -ray spectra and energy deposition in Type Ia supernovae
Anirban Dutta, Andrew Fullard, Wolfgang Kerzendorf +5
Type Ia supernovae (SNe Ia) are powered by the radioactive decay of isotopes such as Ni and Co, making their -ray spectra useful probes of the explosion mechanism…
Analyzing Stellar and Interstellar Contributions to Polarization: Modeling Approaches for Hot Stars
R Ignace, A G Fullard, G V Panopoulou +3
Linear polarimetry of unresolved stars is a powerful method for discerning or constraining the geometry of a source and its environment, since spherical sources produce no net pola…
Introducing STARDIS: An Open and Modular Stellar Spectral Synthesis Code
Joshua V. Shields, Wolfgang Kerzendorf, Isaac G. Smith +7
We introduce a new 1D stellar spectral synthesis Python code called stardis. stardis is a modular, open-source radiative transfer code that is capable of spectral synthesis from ne…
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…
