Abstract (from CDS):

We present the EROS nearby supernova (z∼0.02-0.2) search and the analysis of the first year of data (1997). A total of 80 square degrees were surveyed. Eight supernovae were detected, four of which were spectroscopically identified as type Ia supernovae. The search efficiency was determined with a Monte-Carlo simulation taking into account the efficiencies for both supernova detection and host galaxy identification. Assuming that for a given galaxy the supernova rate is proportional to the galactic luminosity, we compute a type Ia supernova explosion rate of: R=0.44–0.21+0.35–0.07+0.13h2/1010L☉B/100yrs at an average redshift of ∼0.1 where the errors are respectively statistical and systematic (type misidentification included).
