ON THE USE OF EMPIRICAL BOLOMETRIC CORRECTIONS FOR STARS
- Harvard-Smithsonian Center for Astrophysics, 60 Garden St., Cambridge, MA 02138 (United States)
When making use of tabulations of empirical bolometric corrections for stars (BC{sub V}), a commonly overlooked fact is that while the zero point is arbitrary, the bolometric magnitude of the Sun (M{sub bol,sun}) that is used in combination with such tables cannot be chosen arbitrarily. It must be consistent with the zero point of BC{sub V} so that the apparent brightness of the Sun is reproduced. The latter is a measured quantity, for which we adopt the value V{sub sun} = -26.76 {+-} 0.03. Inconsistent values of M{sub bol,sun} are listed in many of the most popular sources of BC{sub V}. We quantify errors that are introduced by failure to pay attention to this detail. We also take the opportunity to reprint the BC{sub V} coefficients of the often used polynomial fits by Flower, which were misprinted in the original publication.
