Title: The Nova Rate in Galaxies of Different Hubble Type
Abstract:
We propose to continue a monthly imaging program at the 0.9m to
determine the nova rate in several galaxies of different Hubble type.
Ciardullo et al. (1990) claim that the nova rates in galaxies of
different Hubble type are very similar when normalized to the total
galaxy K-band luminosity. However, Della Valle et al. (1994) claim the
rates to be different by up to a factor of four, with early-type
galaxies being deficient in novae. Since nova rates depend on several
properties of the stellar population they derive from, one might expect
some variations. The observations proposed here will provide much
better statistics on several Local Group galaxies than presently exists
in order to improve the nova rate estimates in a variety of stellar
populations, in particular in M33 and the disk of M31. This data will
also be used in an NSF-funded research-based science education program
(TLRBSE) operated by NOAO, wherein middle- and high- school science
students learn astronomy and inquiry-based learning skills by
participating in an actual research program. This request represents
the continuation of the approved program from prior semesters.
