Absolute Magnitude Distributions And Light Curves Of Stripped-Envelope Supernovae, D. Richardson, D. Branch, E. Baron

Faculty and Staff Publications

The absolute visual magnitudes of three Type IIb, 11 Type Ib, and 13 Type le supernovae (collectively known as stripped-envelope supernovae) are studied by collecting data on the apparent magnitude, distance, and interstellar extinction of each event. Weighted and unweighted mean absolute magnitudes of the combined sample, as well as various subsets of the sample, are reported. The limited sample size and the considerable uncertainties, especially those associated with extinction in the host galaxies, prevent firm conclusions regarding differences between the absolute magnitudes of supernovae of Types Ib and Ic, and regarding the existence of separate groups of over-luminous and …
