Type Ia supernovae in Lyon groups of galaxies.

ROOD H.J.

Abstract (from CDS):

Two galaxies with observed type Ia supernovae have been identified in each of three Lyon groups of galaxies not associated with the Virgo cluster. The difference of well-determined apparent magnitudes at lihgt curve maximum of the supernovae in each group is delta-B </= 0.2 mag, delta-V </= 0.2 mag. Previously, Branch and Tammann found that the observed apparent magnitudes at maximum light for type Ia supernovae in three galaxies, each with two observed supernovae, are nearly identical. The consistency of these two independent results further suggests that the set of all type Ia supernovae contains a large subset of 'standard candles'.
