A large-scale magnetic field produced by a solar-like dynamo in binary neutron star mergers [PDF]

open access: yesNature Astronomy, 2023
The merger of two neutron stars launches a relativistic jet, which must be driven by a strong large-scale magnetic field. However, the magnetohydrodynamical mechanism required to build up this magnetic field remains uncertain.

Multi-messenger Observations of a Binary Neutron Star Merger [PDF]

open access: yesProceedings of Multifrequency Behaviour of High Energy Cosmic Sources - XIII — PoS(MULTIF2019), 2019
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors.

Dock-able linear and homodetic di, tri, tetra and pentapeptide library from canonical amino acids: SARS-CoV-2 Mpro as a case study

open access: yesJournal of Pharmaceutical Analysis, 2023
Peptide-based therapeutics are increasingly pushing to the forefront of biomedicine with their promise of high specificity and low toxicity. Although noncanonical residues can always be used, employing only the natural 20 residues restricts the chemical ...

Close Binary Companions to APOGEE DR16 Stars: 20,000 Binary-star Systems Across the Color–Magnitude Diagram [PDF]

open access: yesAstrophysical Journal, 2020
Many problems in contemporary astrophysics—from understanding the formation of black holes to untangling the chemical evolution of galaxies—rely on knowledge about binary stars.

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.

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.

Formation of binary black holes similar to GW190521 with a total mass of ∼150 M⊙ from Population III binary star evolution [PDF]

open access: yes, 2020
In case of zero metal (population III) stars, we show that total mass of binary black holes from binary population III star evolution can be $\sim 150 \,M_{\odot}$, which agrees with mass of a binary black hole, GW190521 recently discovered by LIGO/Virgo.

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.
