Asteroseismology of close binary stars [PDF]

Proceedings of the International Astronomical Union, 2007
In this review paper, we summarise the goals of asteroseismic studies of close binary stars. We first briefly recall the basic principles of asteroseismology, and highlight how the binarity of a star can be an asset, but also a complication, for the ...

Quantitative spectroscopy of close binary stars [PDF]

Proceedings of the International Astronomical Union, 2011
The method of spectral disentangling has now created the opportunity for studying the chemical composition in previously inaccessible components of binary and multiple stars.

The Close Binary Frequency of Wolf-Rayet Stars as a Function of Metallicity in M31 and M33 [PDF]

Proceedings of the International Astronomical Union, 2014
Massive star evolutionary models generally predict the correct ratio of WC-type and WN-type Wolf–Rayet stars at low metallicities, but underestimate the ratio at higher (solar and above) metallicities. One possible explanation for this failure is perhaps

Dynamical origin of S-type planets in close binary stars [PDF]

Monthly notices of the Royal Astronomical Society, 2018
Understanding the origin of planets that have formed in binary stars is fundamental to constrain theories of binary and planet formation. The planet occurrence rate in binaries with a separation $\lesssim 50$ AU is only $\sim$ one third that of wider ...

Radial Velocity Studies of Close Binary Stars. XV [PDF]

The Astronomical Journal, 2008
Radial-velocity measurements and sine-curve fits to the orbital radial velocity variations are presented for the last eight close binary systems analyzed the same way as in the previous papers of this series: QX And, DY Cet, MR Del, HI Dra, DD Mon, V868 ...

Terrestrial Planet Formation Surrounding Close Binary Stars [PDF]

Icarus, 2006
Disk material has been observed around both components of some young close binary star systems. It has been shown that if planets form at the right places within such disks, they can remain dynamically stable for very long times.

Classification of close binary stars using recurrence networks. [PDF]

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019
Close binary stars are binary stars where the component stars are close enough such that they can exchange mass and/or energy. They are subdivided into semidetached, overcontact, or ellipsoidal binary stars.

Rotation in Close Binary Stars [PDF]

Highlights of Astronomy, 1980
In binary stars of short period, axial rotation of the components tends to be synchronized with the orbital revolution. Rotation of B. and A stars is therefore slowed down, while for the later-type stars, it is accelerated. This latter fact probably contributes to the phenomenon of the RS CVn stars.
