Studying VLOCV twin compact stars with binary mergers [PDF]

Physical Review D, 2021
GW170817 has provided valuable constraints on the equations of state of merging binary neutron stars, which can be considered as the most probable candidate for the source of gravitational waves. On the other hand, these natural laboratories of extreme temperature and density may lead to the estimation of some exotic matter like {deconfined quark ...

The Death of Compact Binary Stars

Astrophysics and Space Science, 1997
Merging rates for compact binaries (double neutron stars or black holes) are calculated based on modern concepts of binary star evolution. It is found that the first laser interferometers, with rms sensitivities of 10-21 at a frequency of 100 Hz, can detect 10-700 black holes and only ∼1 neutron star coalescences in a 1-year integration time.

Particle acceleration in compact binary stars

Advances in Space Research, 1984
Abstract There may be as many binary neutron stars in the Galaxy as there are pulsars. Their rotational energy can be converted into beams of cosmic rays if there is enough coupling between the corotating magnetosphere and the impinging plasma, in a manner similar to the sparking of a grindstone.

Interactive stars: Normal and compact stars in close binaries

AIP Conference Proceedings, 1990
The missions planned for the 1990’s will greatly expand our knowledge of close binary systems and the physical phenomena that can be studied in a member of a close binary, from stellar active regions to the highest density black hole candidates known.

Chirping compact stars: gravitational radiation and detection degeneracy with binaries

Journal of Cosmology and Astroparticle Physics, 2023
Abstract Compressible, Riemann S-type ellipsoids can emit gravitational waves (GWs) with a chirp-like behavior (hereafter chirping ellipsoids, CELs). We show that the GW frequency-amplitude evolution of CELs (mass ∼ 1 M⊙, radius ∼ 103 km, polytropic equation of state with index n ≈ 3) is indistinguishable from that emitted by double ...

Compact Stars In and Out of Binaries

1995
The Very Large Telescope will allow us to determine more orbital periods and component masses of cataclysmic variables, low-mass X-ray binaries and high-mass X-ray binaries. These are required to put evolutionary models for these systems on a quantitative footing.

Accretion effects on compact members of binary stars

Journal of Astrophysics and Astronomy, 1988
We explore the change in the period of axial rotation and in the radius of a magnetized compact star in a binary system, induced by the accretion on it of mass with angular momentum from the surface of its non-compact companion. No specific assumption is made concerning the accretion model, and the primary’s interior is described by the Fermi-Dirac ...

Binary Compact Star Mergers and the Phase Diagram of Quantum Chromodynamics

2020
This article is dedicated to one of my doctor fathers, Prof. Dr. Dr. h.c. mult. Walter Greiner, whom I first met during my undergraduate studies at the Goethe University Frankfurt in 1990. During this time Walter Greiner gave his legendary 5-semester course on theoretical physics and I had the fortune to be able to attend his first lecture on Mechanic ...
