The Prevalence and Influence of Circumstellar Material around Hydrogen-rich Supernova Progenitors

The Prevalence and Influence of Circumstellar Material around Hydrogen-rich Supernova Progenitors

Narrow transient emission lines (flash-ionization features) in early supernova (SN) spectra trace the presence of circumstellar material (CSM) around the massive progenitor stars of core-collapse SNe. The lines disappear within days after the SN explosion, suggesting that this material is spatially...
