چکیده

The photometric and spectroscopic data for three double-lined detached eclipsing binaries were collected from the spectral surveys. light radial velocity curves of each binary system simultaneously analyzed by using Wilson-Devinney (WD) code, absolute physical orbital parameters these derived. masses both components ASASSN-V J063123.82+192341.9 found to be $M_1 = 1.088 \pm 0.016$ $M_2 0.883 0.016\ M_{\odot}$; those ASAS J011416+0426.4 determined 0.934 0.046$ 0.754 0.043 MW Aur derived 2.052 0.196$ 1.939 0.193\ M_{\odot}$. At last, evolutionary status was discussed based on their theoretical stellar models. Keywords: Stars: binaries: $-$ stars: fundamental parameters$-$ evolution individual: J063123.82+192341.9,

Absolute dimensions of eclipsing binaries***

Context. Double-lined, detached eclipsing binaries are our main source for accurate stellar masses and radii. This paper is the first in a series with focus on the upper half of the main-sequence band and tests of 1–2 M evolutionary models. Aims. We aim to determine absolute dimensions and abundances for the detached eclipsing binary V1130 Tau, and to perform a detailed comparison with results ...

Absolute dimensions of detached eclipsing binaries . I . The metallic - lined system WWAurigae

WWAurigae is a detached eclipsing binary composed of two metallic-lined A-type stars orbiting each other every 2.5 days. We have determined the masses and radii of both components to accuracies of 0.4% and 0.6%, respectively. From a cross-correlation analysis of high-resolution spectra we find masses of 1.964± 0.007M⊙ for the primary star and 1.814±0.007M⊙ for the secondary star. From an analys...

Physical parameters and multiplicity of five southern close eclipsing binaries

Aims. Detect tertiary components of close binaries from spectroscopy and light curve modelling; investigate light-travel time effect and the possibility of magnetic activity cycles; measure mass-ratios for unstudied systems and derive absolute parameters. Methods. We carried out new photometric and spectroscopic observations of five bright (〈V〉 < 10.5 mag) close eclipsing binaries, predominantl...

Light curve solutions for bright detached eclipsing binaries in SMC: absolute dimensions and distance indicators

This paper presents a careful and detailed light curve analysis of bright detached eclipsing binaries (DEB) in the Small Magellanic Cloud, discovered by OGLE collaboration, on the basis of recently available difference image analysis (DIA) photometry. The 19 binaries brighter than 16.4 mag in I band and with the depth of primary and secondary eclipse greater than 0.25 mag were investigated. The...

Effective temperature of detached eclipsing binaries from Hipparcos parallax

Effective temperatures of detached eclipsing binaries computed through Hipparcos trigonometric parallaxes are compared with the photometric determinations. The former are based on the values of the radius, the apparent visual magnitude and the bolometric correction of the star, whereas the latter are obtained from standard calibrations using Strömgren or Johnson colour indices. The working samp...
