Properties of the Binary Neutron Star Merger GW170817 [PDF]

open access: yes, 2018
On August 17, 2017, the Advanced LIGO and Advanced Virgo gravitational-wave detectors observed a low-mass compact binary inspiral. The initial sky localization of the source of the gravitational-wave signal, GW170817, allowed electromagnetic ...

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 ...

Binary star formation and the outflows from their discs [PDF]

open access: yes, 2017
We carry out magnetohydrodynamical simulations with FLASH of the formation of a single, a tight binary ($a\sim$2.5 AU) and a wide binary star ($a\sim$45 AU).

The distance variation due to mass transfer and mass loss in (13.6+8) Mand (13+10) M binary star systems

open access: yesIraqi Journal of Physics, 2019
In this research the change in the distance of the two stars in two binary star systems (13.6+8)M8and (13+10)M8 was studied, through the calculations the value  (rate of mass transfer) of the two phases of dynamical stages of mass which are mass loss ...

K2-136: A Hyades Binary Star with a Neptune-sized Planet [PDF]

open access: yes, 2017
We report the discovery of a Neptune-size planet (Rp = 3.0 Re) in the Hyades Cluster. The host star is in a binary system, comprising a K5V star and M7/8V star with a projected separation of 40 AU.

Unresolved Binaries and Multiples in the Intermediate Mass Range in Open Clusters: Pleiades, Alpha Per, Praesepe, and NGC 1039

open access: yesThe Astronomical Journal, 2023
In this study, we continue our project to search for unresolved binary and multiple systems in open clusters exploiting the photometric diagram (H–W2)–W1 versus W2–(BP–K) first introduced in Malofeeva et al. In particular, here we estimate the binary and

PRELIMINARY RESULTS OF MODELING OF LIGHT CURVES OF WW AND

open access: yesOdessa Astronomical Publications, 2017
In this work we present the preliminary results of modeling of Olson’s lybv light curves of an Algol-type binary WW And. A model of a binary star containing an accretion disk around the primary star is deployed.

Binary Neutron Star Mergers After GW170817

open access: yesFrontiers in Astronomy and Space Sciences, 2020
The first combined detection of gravitational waves and electromagnetic signals from a binary neutron star (BNS) merger in August 2017 (an event named GW170817) represents a major landmark in the ongoing investigation of these extraordinary systems.

Properties of Binary Systems in a One-dimensional Approximation

open access: yesThe Astrophysical Journal, 2023
Evolutionary calculations for stars in close binary systems are in high demand to obtain better constraints on gravitational-wave source progenitors, understand transient events from stellar interactions, and more.

Constraints on the speed of sound of dense nuclear matter through the tidal deformability of neutron stars [PDF]

open access: yesEPJ Web of Conferences, 2021
One of the greatest interest and open problems in nuclear physics is the upper limit of the speed of sound in dense nuclear matter. Neutron stars, both in isolated and binary system cases, constitute a very promising natural laboratory for studying this ...
