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.

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 ...

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

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.

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.

Three-dimensional simulations of neutrino-driven core-collapse supernovae from low-mass single and binary star progenitors [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We present a suite of seven 3D supernova simulations of non-rotating low-mass progenitors using multi-group neutrino transport. Our simulations cover single star progenitors with zero-age main sequence masses between $9.6 M_\odot$ and $12.5 M_\odot$ and (

The Dynamics of Binary Neutron Star Mergers and GW170817 [PDF]

open access: yes, 2020
With the first observation of a binary neutron star merger through gravitational waves and light GW170817, compact binary mergers have now taken the center stage in nuclear astrophysics.

Nuclear Physics with Gravitational Waves from Neutron Stars Disrupted by Black Holes

open access: yesThe Astrophysical Journal Letters, 2023
Gravitational waves from neutron star–black hole (NSBH) mergers that undergo tidal disruption provide a potential avenue to study the equation of state of neutron stars and hence the behavior of matter at its most extreme densities.

The short orbital period binary star at the heart of the planetary nebula M 3-1★ [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2018
We present the discovery of a 3h5m orbital-period binary star at the heart of the planetary nebula M 3-1 - the shortest period photometrically-variable central star known and second only to V458 Vul, in general.
