The eclipsing binary star RZ Cassiopeiae [PDF]

open access: yesAstronomy & Astrophysics, 2008
Aims. We test the hypothesis that the oEA star RZ Cas has undergone a transient phase of rapid mass-transfer in 2000/2001. Methods. We analyze a time series of high-resolution spectra of RZ Cas obtained in 2001 and in 2006 for radial velocity (RV) and line profile variations.

Photometric Observations of Eccentric Accretion in Algol-type Binary Stars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
Some Algol-type interacting binary stars exhibit strange photometric variations that can be phase-dependent and/or secular. This paper discusses the possibility of explaining these observed variations as resulting from an accretion structure eclipsing ...

Eclipsing binaries with candidate CP stars [PDF]

open access: yesAstronomy & 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.

New Light Curve Analysis for Large Numbers of Eclipsing Binaries I. Detached and Semi-Detached Binaries [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2010
Several survey observations have produced light curves of more than five thousand eclipsing binaries for last 15 years. Future missions such as the Large Synoptic Survey Telescope (LSST), the Panoramic Survey Telescope and Rapid Response System (Pan ...

EXPECTED LARGE SYNOPTIC SURVEY TELESCOPE (LSST) YIELD OF ECLIPSING BINARY STARS [PDF]

open access: yes, 2011
In this paper, we estimate the Large Synoptic Survey Telescope (LSST) yield of eclipsing binary stars, which will survey ∼20,000 deg2 of the southern sky during a period of 10 years in six photometric passbands to r ∼ 24.5.

A Note on the Physical Quantities of Eclipsing Binary Stars [PDF]

open access: yes
publisherIn the research activities of high school students, they derive the period of luminosity variation from the light curve of eclipsing binary stars and often consider the aspects of the eclipsing binary stars in phenomenological terms. In addition

β Cephei Pulsators in Eclipsing Binaries Observed with TESS

open access: yesThe Astrophysical Journal Supplement Series
The combined strength of asteroseismology and empirical stellar basic parameter determinations for in-depth asteroseismic analysis of massive pulsators in eclipsing binaries shows great potential for treating the challenging and mysterious discrepancies ...

KM UMa: An Active Short-period Detached Eclipsing Binary in a Hierarchical Quadruple System

open access: yesThe Astrophysical Journal
The first detailed photometric and spectroscopic analysis of the G-type eclipsing binary KM UMa is presented, which indicates that the system is a short-period detached eclipsing binary.

Highlights on eclipsing binary variables from Araucaria Project

open access: yesEPJ Web of Conferences, 2015
The Araucaria Project, which main goal is to provide precise determination of the cosmic distance scale, has recently made a set of discoveries involving variable stars in binary systems. Among these discoveries we highlight three: 1% precise measurement
