Abstract:
We conducted an optical CCD search for supernovae in a sample of 142
bright [m(B)≤16mag], nearby (z≤0.03) starburst galaxies over the
period 1988 December to 1991 June, to a limiting R-band magnitude of
18. Five supernovae were found, in all cases outside the host galaxy's
nucleus. We determine supernova rates (in supernova units or SNU) in
the extranuclear regions to be 0.7h2SNU for Type Ia, 0.7h2SNU
for Type Ib/c, and 0.6h2SNU for Type II, with large uncertainties
but upper limits of 2.2h2, 2.5h2, and 1.7h2SNU, respectively.
These rates are similar to those measured in "normal" galaxies. We
found no evidence for a supernova-induced brightening in any galactic
nucleus and, with a few reasonable assumptions, can place upper limits
of 9h2, 12h2, and 7h2SNU on the rates of unobscured supernovae
Types Ia, Ib/c, and II, respectively, inside the nuclei.
