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 ...

Orbital Elements of visual binary stars with very short arcs: With application to double stars from the 1829 southern double star catalog of James Dunlop [PDF]

open access: yes, 2022
Binary double stars are those whose binding energies are less than zero. Obtaining binary star orbits from short arcs has been a long-standing problem in astrophysics.

Probing Gravitational Theories with Eccentric Eclipsing Detached Binary Stars [PDF]

open access: yes, 2014
In this paper, we compare the effects of different theories of gravitation on the apsidal motion of eccentric eclipsing detached binary stars. The comparison is performed by using the formalism of the post-Newtonian parametrization to calculate the ...

Wide binary stars in the Galactic field : a statistical approach [PDF]

open access: yes, 2010
This thesis focuses on the statistical properties of wide binary (WB) star systems in the Galactic field. With projected separations larger than 200 AU and, consequently, having very low binding energies, WB are sensitive probes of the Galactic ...

EL CVn-type binaries - discovery of 17 helium white dwarf precursors in bright eclipsing binary star systems [PDF]

open access: yes, 2014
The star 1SWASP J024743.37−251549.2 was recently discovered to be a binary star in which an A-type dwarf star eclipses the remnant of a disrupted red giant star (WASP 0247−25 B).

Catalogue of Algol type binary stars [PDF]

open access: yes, 2004
A catalogue of (411) Algol-type (semi-detached) binary stars is presented in the form of five separate tables of information. The catalogue has developed from an earlier version by including more recent information and an improved layout.

Kepler Light Curve Modeling of KIC 9788457

open access: yesJournal of Advanced Research in Natural and Applied Sciences, 2023
Eclipsing binary systems are significant objects for astrophysical studies since they offer more accurate fundamental stellar parameters (mass, radius).

Probing the Efficiency of Tidal Synchronization in Outspiralling Double White Dwarf Binaries with LISA

open access: yesThe Astrophysical Journal, 2023
Compact-object binaries including a white dwarf component are unique among gravitational-wave sources because their evolution is governed not just by general relativity and tides, but also by mass transfer.

The First Comprehensive Photometric Study of the Neglected Binary System V345 Cassiopeiae [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
We present the first BVRI CCD photometric observations of V345 Cas made on 22 nights during the observing seasons in 2007-2008. Our light curves, resembling those of EB-type binary stars, are analyzed with the 2003 version of the Wilson- Devinney ...

Progress in Understanding the Nature of SS433

open access: yesUniverse, 2021
SS433 is the first example of a microquasar discovered in the Galaxy. It is a natural laboratory for studies of extraordinarily interesting physical processes that are very important for the relativistic astrophysics, cosmic gas dynamics and theory of ...
