Carbon-enhanced metal-poor stars: a window on AGB nucleosynthesis and binary evolution. II. Statistical analysis of a sample of 67 CEMP-$s$ stars [PDF]
, 2015 Many observed CEMP stars are found in binary systems and show enhanced abundances of $s$-elements. The origin of the chemical abundances of these CEMP-$s$ stars is believed to be accretion in the past of enriched material from a primary star in the AGB ...

Binary Neutron Stars with Arbitrary Spins in Numerical Relativity [PDF]
, 2015 We present a code to construct initial data for binary neutron star systems in which the stars are rotating. Our code, based on a formalism developed by Tichy, allows for arbitrary rotation axes of the neutron stars and is able to achieve rotation rates ...

EVOLUTION OF MASS FUNCTIONS OF COEVAL STARS THROUGH WIND-MASS LOSS AND BINARY INTERACTIONS [PDF]
, 2015 Accurate determinations of stellar mass functions and ages of stellar populations are crucial to much of astrophysics. We analyze the evolution of stellar mass functions of coeval main-sequence stars, including all relevant aspects of single and binary ...

The Evolution of Compact Binary Star Systems
Living Reviews in Relativity, 2014 We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Mergings of compact-star binaries are expected to be the most important sources for forthcoming gravitational-wave

The Evolution of Massive Binary Stars [PDF]
Annual Review of Astronomy and Astrophysics, 2023 Massive stars play a major role in the evolution of their host galaxies and serve as important probes of the distant Universe. It has been established that the majority of massive stars reside in close binaries and interact with their companion stars ...

Which black hole formed first? Mass-ratio reversal in massive binary stars from gravitational-wave data [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Population inference of gravitational-wave catalogs is a useful tool to translate observations of black hole mergers into constraints on compact-binary formation.

The Evolution of Compact Binary Star Systems
Living Reviews in Relativity, 2006 We review the formation and evolution of compact binary stars consisting of white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and BHs are thought to be the primary astrophysical sources of gravitational waves (GWs) within the ...

The origin and evolution of magnetic white dwarfs in close binary stars [PDF]
Nature Astronomy, 2021 The origin of magnetic fields in white dwarfs remains a fundamental unresolved problem in stellar astrophysics. In particular, the very different fractions of strongly (more than about a megagauss) magnetic white dwarfs in evolutionarily linked ...

Different to the core: the pre-supernova structures of massive single and binary-stripped stars [PDF]
Astronomy & Astrophysics, 2021 The majority of massive stars live in binary or multiple systems and will interact during their lifetimes, which helps to explain the observed diversity of core-collapse supernovae.

A Distance Determination to the Small Magellanic Cloud with an Accuracy of Better than Two Percent Based on Late-type Eclipsing Binary Stars [PDF]
Astrophysical Journal, 2020 We present a new study of late-type eclipsing binary stars in the Small Magellanic Cloud (SMC) undertaken with the aim of improving the distance determination to this important galaxy.
