J/ApJ/673/999       Supernova and host galaxies metallicities    (Prieto+, 2008)

Characterizing supernova progenitors via the metallicities of their host galaxies, from poor dwarfs to rich spirals. Prieto J.L., Stanek K.Z., Beacom J.F. <Astrophys. J., 673, 999-1008 (2008)> =2008ApJ...673..999P
ADC_Keywords: Supernovae ; Abundances Keywords: supernovae: general Abstract: 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 galaxies span a range of oxygen abundance from 12+log(O/H)=7.9 to 9.3 (∼0.1-2.7 solar) and a range in absolute magnitude from MB=-15.2 to -22.2. To reduce the various observational biases, we select a subsample of well-characterized supernovae in the redshift range from 0.01 to 0.04, which leaves us with 58 SNe II, 19 SNe Ib/c, and 38 SNe Ia. Description: We use the SAI supernova catalog (Tsvetkov et al. 2004, Cat. II/256) to obtain the main properties of supernovae (name, classification, right ascension, declination, redshift) and their host information when available (galaxy name, right ascension, declination, redshift).
