The Evolution of Massive Close Binaries

Astrophysics and Space Science, 2005
We present results of evolutionary computations for massive close binaries with the Brussels simultaneous evolution code for conservative and non-conservative Roche lobe overflow (RLOF). We discuss mass transfer in massive close binaries during phases of RLOF, common envelope, spiral-in and merging.

Structure of close binaries

Astrophysics and Space Science, 1972
Models of uniformly rotating non-synchronous binary polytropes have been calculated and compared with the results obtained from the Roche model. It is found that the relative dimensions of the non-synchronous systems are adequately portrayed by a Roche model but the degree of central condensation affects the minimum separation by an amount which is ...

Accretion and Evolution in Close Binaries

Astrophysics and Space Science, 1996
The discovery of X-ray binary systems in the 1960’s opened up stellar evolution theory by revealing further endpoints in addition to white dwarfs. This review summarises recent progress in studies of stellar-evolutionary processes that lead to X-ray binaries themselves, the mass transfer rates that power them, and the accretion processes which convert ...

Apsidal Motion in Close Binaries

2000
Tidal effects in close binaries are well known as an important source of information on stellar interiors. Such information can also be obtained for a single star if it pulsates, like radial or non-radial pulsating stars. In the last thirty years many different models for the structure and evolution of the stars have been performed.

Supernovae in close binaries

Astrophysics and Space Science, 1974
The impact of a supernova shell onto 2.82M⊙ and 20.0M⊙ main-sequence stars is investigated for various initial orbital separations, and various supernova shell masses and velocities. The inelastic collision between the star and the supernova shell, the shock propagation into the companion star, and other forms of momentum transfer such as the rocket ...
