SummaryBinary stars are the main source of fundamental data on stellar masses and radii (M, R). Considerable progress has been made in recent years in the quality and quantity of such data, and stellar masses and radii of high accuracy have led to a number of qualitatively new and interesting results on the properties and evolution of normal stars. This paper reviews the current status of fundamentalM andR determinations which (i) have errors ⩽ 2%, the limit for non-trivial results in many… 
Accurate masses and radii of normal stars: modern results and applications
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
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 eclipsing
Stellar Masses and Radii as Constraints on Stellar Models
The current status of empirical data on stellar masses and radii of sufficient accuracy to give constraints on stellar models is reviewed. Results from the best-studied eclipsing binaries can already
We have executed a survey of nearby, main-sequence A-, F-, and G-type stars with the CHARA Array, successfully measuring the angular diameters of forty-four stars with an average precision of ~1.5%.
A study of binary stars: Absolute properties of the eclipsing binary star RT Coronae Borealis
We present an analysis of existing photometric observations in U, B, and V, and a new light curve in V, as well as spectroscopic observations, of the 5.1 day period, double-lined main-sequence
Stellar Diameters and Temperatures. II. Main-sequence K- and M-stars
We present interferometric angular diameter measurements of 21 low-mass, K- and M-dwarfs made with the CHARA Array. This sample is enhanced by adding a collection of radius measurements published in
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 effective
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 stellar
Fundamental properties of low-mass stars in eclipsing binary systems
Eclipsing binary systems offer a unique opportunity to accurately measure the fundamental properties of stars. In the past years, masses and radii of low-mass stars in these systems have been
Fundamental properties of lower main-sequence stars
The field of exoplanet research has revitalized interest in M dwarfs, which have become favorite targets of Doppler and transit surveys. Accurate measurements of their basic properties such as


Absolute dimensions and masses of eclipsing binaries. V: IQ Persei
New photometric and spectroscopic observations of the 1.7 day eclipsing binary IQ Persei (B8 + A6) have been analyzed to yield very accurate fundamental properties of the system. Reticon
Star clusters and stellar evolution. I. Improved synthetic color-magnitude diagrams for the oldest clusters.
New stellar evolutionary sequences extending from the main sequence to the base of the red giant branch have been computed assuming two values of the helium abundance, Y = 0.2, for each of the
TZ Fornacis : stellar and tidal evolution in a binary with a fully-fledged red giant (Absolute dimensions of eclipsing binaries. XVII)
This paper provides the first highly precise determination of absolute dimensions for a normal giant star. We present new radial velocity curves, high-resolution spectroscopy, and complete uvby light
Normal and abnormal binary frequencies
It is becoming apparent that most normal main-sequence stars are members of both short-period and long-period systems. Let us cite some evidence. Petrie ( 1960) showed from a sample of 1752 stars
The main properties of the evolution of intermediate- and high-mass stars are reviewed, focusing on a few issues tightly related to the interpretation of population I Cepheid stars. The classical
New strong evidence for the importance of convective overshooting in intermediate-mass stars
Major differences between current series of stellar evolution calculations concern their opacities and treatment of convection. Accurate mass, radius, luminosity, and abundance data from eclipsing

V792 Her is an eclipsing RS CVn binary with an orbital period of 27.54 days whose components have spectral types of K0 III and F2 IV. New spectroscopic observations combined with existing photometry
The development of the red giant branch. II - Astrophysical properties
Evolutionary sequences developed in another paper are used here to investigate the properties of the red giant branch (RGB) phase transition. Results are found for compositions in the range Y(MS)
