Neutron Star Mergers and the Quark Matter Equation of State [PDF]

EPJ Web of Conferences, 2022
As neutron stars merge they can approach very high nuclear density. Here, we summarized recent results for the evolution and gravitational wave emission from binary-neutron star mergers using a a variety of nuclear equations of state with and without a ...

Potential Importance of Binary Evolution in UV-Optical Spectral Fitting of Early-Type Galaxies

, 2013
Binaries are very common in galaxies, and more than half of Galactic hot subdwarf stars, which are thought as a possible origin of UV-upturn of old stellar populations, are found in binaries.

How THC works: Explaining ligand affinity for, and partial agonism of, cannabinoid receptor 1

iScience
Summary: Interaction with cannabinoid receptor 1 (CB1) partially determines the bioactivity of the phytocannabinoids. Consequently, there has also been significant effort directed toward preparing synthetic cannabinoids with either enhanced agonistic or ...

Dynamical population synthesis: Constructing the stellar single and binary contents of galactic field populations

, 2011
[abridged] The galactic field's late-type stellar single and binary population is calculated on the supposition that all stars form as binaries in embedded star clusters.

Binary Neutron Star Mergers After GW170817

Frontiers 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.

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

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

The origin of very wide binary systems [PDF]

, 2009
The majority of stars in the Galactic field and halo are part of binary or multiple systems. A significant fraction of these systems have orbital separations in excess of thousands of astronomical units, and systems wider than a parsec have been ...

PRELIMINARY RESULTS OF MODELING OF LIGHT CURVES OF WW AND

Odessa 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.

Discovery of a bright eclipsing cataclysmic variable [PDF]

, 2007
We report on the discovery of J0644+3344, a bright deeply eclipsing cataclysmic variable (CV) binary. Spectral signatures of both binary components and an accretion disk can be seen at optical wavelengths.

On the universal outcome of star-formation: Is there a link between stars and brown-dwarfs?

, 2003
(abridged) The recent evidence obtained by Briceno et al. that star-formation in Taurus-Auriga (TA) may be producing significantly fewer brown dwarfs (BDs) per star than the ONC is investigated by setting up a realistic model stellar plus BD population ...
