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).
