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.
