Gravity darkening in binary stars [PDF]
Astronomy & Astrophysics, 2012 Context.Interpretation of light curves of many types of binary stars requires the inclusion of the (cor)relation between surface brightness and local effective gravity. Until recently, this correlation has always been modeled by a power law relating the flux or the effective temperature and the effective gravity, namely T_eff g_eff^ . Aims. We look

Hypervelocity Collisions of Binary Stars at the Galactic Centre [PDF]
, 2006 Recent surveys have identified seven hypervelocity stars (HVSs) in the halo of the Milky Way. Most of these stars may have originated from the breakup of binary star systems by the nuclear black hole SgrA*.

The Formation of Binary Stars [PDF]
Symposium - International Astronomical Union, 1981 The speed and storage capacity of present-day computers have stimulated the development of numerical techniques allowing the investigation of three-dimensional gas dynamical problems of astronomical interest. Of the problems that can be attacked with these techniques, that of the formation of binaries has historically attracted the greatest interest ...

Binary Stars in Upper Scorpius [PDF]
The Astronomical Journal, 2019 Abstract To address the statistics of binary stars in the 8 Myr old Upper Scorpius (USco) star formation region, we conducted a speckle interferometric survey of 614 association members more massive than 0.4 (spectral types earlier than M3V) based on the list of Luhman et

Population synthesis of neutron stars, strange (quark) stars and black holes [PDF]
, 2000 We compute and present the distribution in mass of single and binary neutron stars, strange stars, and black holes. The calculations were performed using a stellar population synthesis code.

Building and Calibrating the Binary Star Population Using Kepler Data [PDF]
, 2020 Modeling binary star populations is critical to linking the theories of star formation and stellar evolution with observations. In order to test these theories, we need accurate models of observable binary populations. The Kepler Eclipsing Binary Catalog (KEBC), with its estimated $>$90% completeness, provides an observational anchor on binary ...

On the Detection of Binary Be Stars [PDF]
Symposium - International Astronomical Union, 1976 Possible methods for detecting the presence of a cool companion to a Be star are discussed. Photometric observations are shown to be incapable of detecting companions in all but the most extreme cases. Spectroscopic investigation is also unlikely to yield many new discoveries.

The evolution of massive binary systems [PDF]
Serbian Astronomical Journal, 2020 The evolution of massive stars in close binary systems is significantly different from single star evolution due to a series of interactions between the two stellar components.
