NED Abstract

Copyright by American Institute of Physics. 1997AstL...23..644G Calibration of the Brightest Red and Blue Stars as Distance Indicators for Late-Type Galaxies Ts. B. Georgiev, B. I. Bilkina, and N. M. Dencheva Rozhen National Astronomical Observatory, BG-4700, Smolyan, Bulgaria Received May 5, 1996; in final form, May 20,1997 Abstract - Current data for 17 nearby galaxies are used to calibrate different forms of the brightest-star method. The relations between the distance modulus, (m-M)_0_, the total magnitude of the galaxy, B(g)_0_, and the mean magnitudes of its three brightest red and blue stars, V(3R)_0_ and B(3B)_0_, are (m-M)_0_ = 3.73 - 0.38B(g)_0_ + 1.40V(3R)_0_; (m-M)_0_ = 3.83 - 0.61B(g)_0_ + 1.59B(3B)_0_; (m-M)_0_ = 3.60 - 0.45B(g)_0_ + 1.06V(3R)_0_ + 0.40B(3B)_0_. The results are applied to a sample of 15 other galaxies, including three presumed members of the Virgo cluster. The distance determination for Sextans B, IC 10, Ho II, Ho IX, NGC 4523, and other galaxies is discussed. It is concluded that the method has a satisfactory accuracy (.3^m^-.4^m^) and is reliable up to distances of the order of 20 Mpc.
