A Search for Exoplanets in Short-Period Binary Star Systems [PDF]
Journal of Astronomy and Space Sciences, 2012 This paper reports the progress of a search for exoplanets with S-type orbits in short-period binary star systems. The selected targets have stellar orbital periods of just a few days. These systems are eclipsing binaries so that exoplanet transits, if

Binary Be Stars and Be Binaries [PDF]
Symposium - International Astronomical Union, 1992 Two hypotheses have been put forward for the rôle of binarity in Be stars: (1) All Be stars are interacting binaries. (2) Roughly one-half of the observed Be stars are post-mass exchange binaries with compact companions. Contrary to (1), (2) does not attempt to explain also the existence of disks in Be stars.

Binary interaction dominates the evolution of massive stars [PDF]
, 2012 The presence of a nearby companion alters the evolution of massive stars in binary systems, leading to phenomena such as stellar mergers, X-ray binaries and gamma-ray bursts.

Galaxies, 2018 The increase in discovered close binary central stars of planetary nebulae is leading to a sufficiently large sample to begin to make broader conclusions about the effect of close binary stars on common envelope evolution and planetary nebula formation ...

The Astronomical Journal, 2023 We present orbital elements for 22 single-line binaries, nine of them studied for the first time, determined from a joint spectroscopic and astrometric solution.

Ultracompact binary stars [PDF]
Physics Today, 2006 Double stars with tight, rapid orbits enable astronomers to study issues ranging from binary-star evolution to the internal structure of white dwarfs and neutron stars. In addition, they may emit directly observable gravitational waves.

Hypervelocity stars from young stellar clusters in the Galactic Centre [PDF]
, 2017 The enormous velocities of the so called hypervelocity stars (HVSs) derive, likely, from close interactions with massive black holes, binary stars encounters or supernova explosions.

Symposium - International Astronomical Union, 1997 Low and intermediate mass stars leave the Asymptotic Giant Branch (AGB) when the mass in their H-rich envelope is less than about 0.01 M⊙, and the high mass loss drops several orders of magnitude. The central star rapidly evolves to the left part of the HR diagram along a track of constant luminosity (e.g. Schönberner 1983).

Carbon-enhanced metal-poor stars: a window on AGB nucleosynthesis and binary evolution. I. Detailed analysis of 15 binary stars with known orbital periods [PDF]
, 2015 AGB stars are responsible for producing a variety of elements, including carbon, nitrogen, and the heavy elements produced in the slow neutron-capture process ($s$-elements).

The evolution of wide binary stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We study the orbital evolution of wide binary stars in the solar neighborhood due to gravitational perturbations from passing stars. We include the effects of the Galactic tidal field and continue to follow the stars after they become unbound. For a wide variety of initial semi-major axes and formation times, we find that the number density (stars per ...
