Abstract:
The mass-luminosity relation (MLR) for intermediate-mass stars is
based on data on detached main-sequence double-lined eclipsing
binaries (DM-DLEB). However, there is a notable difference between
the parameters of B0V-G0V components of eclipsing binaries and those
of single stars. Single early-type stars are rapid rotators, whereas
tidal forces produce synchronous rotation in close binaries and all
such pairs are synchronized, so components of close binaries rotate
more slowly. As is well known, stellar rotation changes stellar
evolution and the global parameters of a star.
In this work we collect data on fundamental parameters of stars with
masses m>1.5m☉. They are components of binaries with P>15d and
consequently are not synchronized with the orbital periods and
presumably are rapid rotators. These stars are believed to evolve
similarly with single stars. Modern data on masses, absolute and
bolometric luminosities, radii and temperatures of detached
main-sequence double-lined eclipsing binary components (i.e.
presumably slow rotators) are also collected.
Mass-luminosity, mass-temperature and mass-radius relations of close
and wide binaries are presented, as well as their Hertzsprung-Russell
diagram.
