Statistical Analysis of Early Spectra in Type II and IIb Supernovae
Maider González-Bañuelos, Claudia P. Gutiérrez, LluÃs Galbany +1
We present a comprehensive analysis of the early spectra of type II and type IIb supernovae (SNe) to explore their diversity and distinguishable characteristics. Using 866 publicly…
