Abstract:
This article presents and discusses a critical compilation of
accurate, fundamental determinations of stellar masses and radii. We
have identified 95 detached binary systems containing 190 stars (94
eclipsing systems, and alpha Centauri) that satisfy our criterion that
the mass and radius of both stars be known within errors of ±3%
accuracy or better. All of them are non-interacting systems, and so
the stars should have evolved as if they were single. This sample more
than doubles that of the earlier similar review by Andersen (Astron.
Astrophys. Rev. 3:91-126, 1991), extends the mass range at both ends
and, for the first time, includes an extragalactic binary. In every
case, we have examined the original data and recomputed the stellar
parameters with a consistent set of assumptions and physical
constants.
