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 analyse the evolution of stellar mass functions of coeval main sequence stars including all relevant aspects of single- and binary ...

The Astrophysical Journal, 2023 We present a timing study of the short-period eclipsing cataclysmic variable (CV) HT Cas. Based on new eclipse times derived from our photometric monitoring and archival optical data, combined with historical timings, spanning ∼42 yr, we detect a secular

Close encounters of star–black hole binaries with single stars
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Multibody dynamical interactions of binaries with other objects are one of the main driving mechanisms for the evolution of star clusters. It is thus important to bring our understanding of three-body interactions beyond the commonly employed point-particle approximation.

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.

Evidence for Prolonged Main Sequence Stellar Evolution of F Stars in close binaries [PDF]
, 2001 Binary F stars exhibit large brightness anomaly, which is defined here as the difference between the absolute magnitude from the uvby photometry and the actual absolute magnitude of the star.

Close encounters in young stellar clusters: implications for planetary systems in the solar neighbourhood [PDF]
, 2007 The stars that populate the solar neighbourhood were formed in stellar clusters. Through N-body simulations of these clusters, we measure the rate of close encounters between stars. By monitoring the interaction histories of each star, we investigate the

THE CLOSE BINARY PROPERTIES OF MASSIVE STARS IN THE MILKY WAY AND LOW-METALLICITY MAGELLANIC CLOUDS [PDF]
, 2013 In order to understand the rates and properties of Type Ia and Type Ib/c supernovae, X-ray binaries, gravitational wave sources, and gamma-ray bursts as a function of galactic environment and cosmic age, it is imperative that we measure how the close ...

The Search for Close Binary Evolved Stars [PDF]
International Astronomical Union Colloquium, 1989 AbstractWe report on a search for short-period binary systems composed of pairs of evolved stars. The search is being carried out concurrently with a program to characterize the kinematical properties of two different samples of stars. Each sample has produced one close binary candidate for which further spectroscopic observations are planned.

Merger Conditions of Population III Protostar Binaries
The Astrophysical Journal, 2023 Massive close binary stars with extremely small separations have been observed, and they are possible progenitors of gravitational-wave sources. The evolution of massive binaries in the protostellar accretion stage is key to understanding their formation

The Birth Function for Black Holes and Neutron Stars in Close Binaries [PDF]
Astrophysical Journal, 2020 The mass function for black holes and neutron stars at birth is explored for mass-losing helium stars. These should resemble, more closely than similar studies of single hydrogen-rich stars, the results of evolution in close binary systems.
