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.

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 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.

A radio-pulsing white dwarf binary star [PDF]

open access: yesNature, 2016
White dwarfs are compact stars, similar in size to Earth but approximately 200,000 times more massive. Isolated white dwarfs emit most of their power from ultraviolet to near-infrared wavelengths, but when in close orbits with less dense stars, white ...

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 cosmic merger rate density of compact objects: impact of star formation, metallicity, initial mass function, and binary evolution [PDF]

open access: yes, 2020
We evaluate the redshift distribution of binary black hole (BBH), black hole - neutron star binary (BHNS) and binary neutron star (BNS) mergers, exploring the main sources of uncertainty: star formation rate (SFR) density, metallicity evolution, common ...

A Search for Exoplanets in Short-Period Binary Star Systems [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2012
This paper reports the progress of a search for exoplanets with S-type orbits in short-period binary star systems. The selected targets have stellar orbital periods of just a few days. These systems are eclipsing binaries so that exoplanet transits, if

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

Short Gamma Ray Bursts as possible electromagnetic counterpart of coalescing binary systems [PDF]

open access: yes, 2010
Coalescing binary systems, consisting of two collapsed objects, are among the most promising sources of high frequency gravitational waves signals detectable, in principle, by ground-based interferometers.
