CHARACTERIZING SUPERNOVA PROGENITORS VIA THE METALLICITIES OF THEIR HOST GALAXIES, FROM POOR DWARFS TO RICH SPIRALS

摘要

We investigate how the different types of supernovae are relatively affected by the metallicity of their host galaxy. We match the SAI supernova catalog to the SDSS DR4 catalog of star-forming galaxies with measured metallicities. These supernova host gal
