From Dinuclear Systems to Close Binary Stars: Application to Mass Transfer

Acta Physica Polonica B, 2018
Applying the microscopic nuclear physics ideas to macroscopic stellar systems, we study the evolution of the compact di-stars in mass asymmetry (transfer) coordinate.

CLOSE BINARY SYSTEMS ON LATE EVOLUTIONARY STAGES

Odessa Astronomical Publications, 2017
Observational and theoretical progress in investigations of close binary stars allow to understand the nature and evolution of many types of close binary systems containing peculiar components: Wolf-Rayet stars, white dwarfs neutron stars and black holes.

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

CLOSE-IN STELLAR COMPANIONS IN CLOSE BINARY STARS [PDF]

Publications of The Korean Astronomical Society, 2015
Close binary stars are so close that one component has an effect on the evolution of the other. But how do they form and evolve? This is an unsolved problem. One speculation is that the binary is a part of a hierarchical triple and its orbit shrinks due to interaction with the third component.

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 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 ...

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

Orbital Decay in an Accreting and Eclipsing 13.7 Minute Orbital Period Binary with a Luminous Donor

The Astrophysical Journal Letters, 2023
We report the discovery of ZTF J0127+5258, a compact mass-transferring binary with an orbital period of 13.7 minutes. The system contains a white dwarf accretor, which likely originated as a post–common envelope carbon–oxygen (CO) white dwarf, and a warm

A transiting companion to the eclipsing binary KIC002856960 [PDF]

, 2012
We present an early result from an automated search of Kepler eclipsing binary systems for circumbinary companions. An intriguing tertiary signal has been discovered in the short period eclipsing binary KIC002856960. This third body leads to transit-like

The evolution of close helium star to neutron star binaries [PDF]

Symposium - International Astronomical Union, 2003
We present the evolution of helium stars in binary systems with a 1.4 M⊙ neutron-star companion which will produce double neutron-star binaries, i.e., systems with helium stars more massive than 2.5 M⊙. We found that mass transfer from helium star less massive than ~ 3.3 M⊙ will end up in a common-envelope phase.
