New eclipsing binaries with mercury–manganese stars [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2021
ABSTRACT Eclipsing binary stars are rare and extremely valuable astrophysical laboratories that make possible precise determination of fundamental stellar parameters. Investigation of early-type chemically peculiar stars in eclipsing binaries provides important information for understanding the origin and evolutionary context of their ...

Eclipsing Binary Stars from Space [PDF]

Proceedings of the International Astronomical Union, 2006
We have begun a programme to obtain high-precision photometry of bright detached eclipsing binary (dEB) stars with the Wide field InfraRed Explorer (WIRE) satellite. Due to the small aperture of WIRE only stars brighter than V=6 can be observed.

Asteroseismology of Eclipsing Binary Stars in the Kepler Era [PDF]

, 2014
Eclipsing binary stars have long served as benchmark systems to measure fundamental stellar properties. In the past few decades, asteroseismology - the study of stellar pulsations - has emerged as a new powerful tool to study the structure and evolution ...

Eclipsing binaries with candidate CP stars [PDF]

Astronomy & Astrophysics, 2001
We present a detailed study of an eclipsing binary which had been classied Ap SrCrEu (Hartoog 1976) before being known as a binary. Radial velocities measured at the times of both quadratures allow us to obtain precise masses for both components, while the light curve yields the radii.

Eclipsing binary stars with a delta Scuti component [PDF]

Monthly Notices of the Royal Astronomical Society, 2017
Eclipsing binaries with a δ Sct component are powerful tools to derive the fundamental parameters and probe the internal structure of stars. In this study, spectral analysis of six primary δ Sct components in eclipsing binaries has been performed. Values

KEPLERECLIPSING BINARY STARS. II. 2165 ECLIPSING BINARIES IN THE SECOND DATA RELEASE [PDF]

The Astronomical Journal, 2011
The Kepler Mission provides nearly continuous monitoring of ~156 000 objects with unprecedented photometric precision. Coincident with the first data release, we presented a catalog of 1879 eclipsing binary systems identified within the 115 square degree Kepler FOV. Here, we provide an updated catalog augmented with the second Kepler data release which

Phemenological Modeling of Eclipsing Binary Stars [PDF]

, 2016
We review the method NAV (New Algol Variable) first introduced in 2012Ap.....55..536A, which uses the locally-dependent shapes of eclipses in an addition to the trigonometric polynomial of the second order (which typically describes the "out-of-eclipse" part of the light curve with effects of reflection, ellipticity and O'Connell).

Photometric analysis of eclipsing binary stars

Iraqi Journal of Physics, 2019
In this paper, photometric analysis of two short period group of the eclipsing binaries (RS CVn); RT And and BH Vir is presented. New physical and geometric parameters were obtained by performing two computer modeling.
