NED Abstract

Copyright by American Institute of Physics. 1993AstL...19..147S Nova frequency in galaxies of the Local Group A. S. Sharov P. K. Shternberg State Astronomical Institute (Submitted January 19, 1993) Pis'ma Astron. Zh. 19, 387-400 (May 1993) We estimate the nova frequency in the disk of M 31, its companions M 32 and NGC 205, and M 33 on the basis of observational data obtained in the Crimea and Latvia in 1967-1990. The estimated nova frequency per year is R = 2.9-4.4 in the disk of M 33. R < 0.2 in M32 and NGC 205, and R < 0.4 in M 33. These data lead to the following specific frequencies per unit galaxy luminosity (10^10^L_B_sun_) in the B band: {rho}_B_ = 1.4-1.8 in the disk of M 31, {rho}_B_ < 8.7 in M 32, {rho}_B_< 6.9 in NGC 205, and {rho}_B_ < 1.0 in M 33. These results confirm the strong difference in specific nova frequency between the disk and bulge of M 31 ({rho}_B_ = 24.4-35.1). Similar results are obtained using galaxy luminosities in the IR K band.
