Main sequence spectral and mass calibrations of effective temperature, absolute magnitude, luminosity, surface gravitational potential, surface gravitational acceleration and radius of B-stars

Abstract

The known empirical data of the effective temperature and the absolute magnitude of BV-III stars are analyzed. In this regard, the tabular and analytical spectral calibrations of these parameters are determined for these stars. The empirical relations between the luminosity and mass are determined for BV-III stars. In this regard, the tabular spectral calibrations of the mass, the radius, the surface gravitational potential and the surface gravitational acceleration are determined for BV-III stars. Using these tabular calibrations, the analytical mass and spectral calibrations of their parameters are established for these stars. The areas of the constant value of the surface gravitational potential and the areas of the constant value of the surface gravitational acceleration are found in the analytical mass and spectral calibrations of these parameters. The areas of the first type and the areas of the second type alternately follow each other along the axes of the mass and the spectral type. Also, the areas of the first type and the areas of the second type follow with constant the repetition step along the axes of the surface gravitational potential and the surface gravitational acceleration, respectively.
