Incompressible fluid binary systems with internal flows -- models of close binary neutron star systems with spin [PDF]

open access: bronze, 1998
In this paper we have examined numerically exact configurations of close binary systems composed of incompressible fluids with internal flows.

Tidally trapped pulsations in a close binary star system discovered by TESS [PDF]

open access: yesNature Astronomy, 2020
It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have been searched for, but until now never detected.

Thin shell morphology in the circumstellar medium of massive binaries [PDF]

open access: yes, 2010
We investigate the morphology of the collision front between the stellar winds of binary components in two long-period binary systems, one consisting of a hydrogen rich Wolf-Rayet star (WNL) and an O-star and the other of a Luminous Blue Variable (LBV ...

Stability analysis of the spin evolution fix points in inspiraling compact binaries with black hole, neutron star, gravastar, or boson star components [PDF]

open access: yesPhys. Rev. D 103, 084025 (2021), 2022
Based on the secular spin evolution of black holes, neutron stars, gravastars, or boson stars in precessing compact binaries on eccentric orbit, we identify the aligned and more generic coplanar configurations of the spins and orbital angular momentum as fix points.

Statistical Survey for the Physical Characteristic of Near Contact Binary(NCBs) [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2005
The absolute dimensions and orbital elements of 66 near contact binaries, collected from literatures, have been analyzed to investigate the physical characteristics of the near contact binaries as well as co-relations among physical parameters.

Search for a Black Hole Binary in Gaia DR3 Astrometric Binary Stars with Spectroscopic Data

open access: yesThe Astrophysical Journal, 2023
We report the discovery of a candidate binary system consisting of a black hole (BH) and a red giant branch star in Gaia DR3. This binary system was discovered from 64,108 binary solutions for which both astrometric and spectroscopic data are available ...

Population of Merging Compact Binaries Inferred Using Gravitational Waves through GWTC-3

open access: yesPhysical Review X, 2023
We report on the population properties of compact binary mergers inferred from gravitational-wave observations of these systems during the first three LIGO-Virgo observing runs.

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet

Binary Gravitational Perturbations and Their Influence on the Habitability of Circumstellar Planets

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In order to assess the habitability of planets in binary star systems, not only astrophysical considerations regarding stellar and atmospheric conditions are needed, but orbital dynamics and the architecture of the system also play an important role. Due

Interpreting binary neutron star mergers: describing the binary neutron star dynamics, modelling gravitational waveforms, and analyzing detections [PDF]

open access: yesGeneral Relativity and Gravitation, 2020
Gravitational waves emitted from the coalescence of neutron star binaries open a new window to probe matter and fundamental physics in unexplored, extreme regimes.
