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 α 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… Expand
Absolute masses and radii determination in multiplanetary systems without stellar models
The masses and radii of extrasolar planets are key observables for understanding their interior, formation and evolution. While transit photometry and Doppler spectroscopy are used to measure theExpand
The radius discrepancy in low-mass stars: Single versus binaries
A long-standing issue in the theory of low-mass stars is the discrepancy between predicted and observed radii and effective temperatures. In spite of the increasing availability of very preciseExpand
Radii of Rapidly-Rotating Stars, with Application to Transiting-Planet Hosts
The currently favored method for estimating radii and other parameters of transiting-planet host stars is to match theoretical models to observations of the stellar mean density ρ*, the effectiveExpand
Fundamental properties of nearby single early B-type stars
Fundamental parameters of a sample of 26 apparently slowly-rotating single early B-type stars in the solar neighbourhood are presented and compared to high-precision data from detached eclipsingExpand
Stellar ages, masses and radii from asteroseismic modeling are robust to systematic errors in spectroscopy
The search for twins of the Sun and Earth relies on accurate characterization of stellar and exoplanetary parameters: i.e., ages, masses, and radii. In the modern era of asteroseismology, parametersExpand
Testing models of stellar structure and evolution - I. Comparison with detached eclipsing binaries
We present the results of an analysis aimed at testing the accuracy and precision of the PARSEC v1.2S library of stellar evolution models, in a Bayesian framework, to infer stellar parameters. WeExpand
Modelling binary stars: age, helium abundance and convection parameters
Stellar evolutionary models simulate binary stars well, when the individual stellar mass and the system metallicity are known. Our main goal in this paper is to determine a set of stellar parametersExpand
Observational constraints from binary stars on stellar evolution models
Accurate determinations of masses and radii in binary stars, along with estimates of the effective temperatures, metallicities, and other properties, have long been used to test models of stellarExpand

Accurate, Empirical Radii and Masses of Planets and their Host Stars with Gaia Parallaxes
We present empirical measurements of the radii of 116 stars that host transiting planets. These radii are determined using only direct observables-the bolometric flux at Earth, the effectiveExpand
