Implications for compact stars of a soft nuclear equation of state from heavy-ion data [PDF]

, 2012
We study the implications on compact star properties of a soft nuclear equation of state determined from kaon production at subthreshold energies in heavy-ion collisions.

New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems [PDF]

, 2016
We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orbital elements for the remaining stars because the phase coverage is ...

Bimodal Black Hole Mass Distribution and Chirp Masses of Binary Black Hole Mergers

The Astrophysical Journal Letters, 2023
In binary black hole mergers from isolated binary-star evolution, both black holes are from progenitor stars that have lost their hydrogen-rich envelopes by binary mass transfer.

From a Dinuclear System to Close Binary Cosmic Objects

Astronomy, 2023
Applying the ideas from microscopic objects to macroscopic stellar and galactic systems, the evolution of compact di-stars and di-galaxies is studied in the mass asymmetry coordinate. The formation of stable binary systems is analyzed.

The Formation and Evolution of Compact Stars in Binaries [PDF]

International Astronomical Union Colloquium, 2004
AbstractThe stellar evolutionary processes responsible for the formation of compact objects in interacting binary systems and their evolution are described. The common envelope phase plays a crucial role in their formation and angular momentum losses associated with magnetic braking and/or mass loss are important for their evolution.

CHIME Discovery of a Binary Pulsar with a Massive Nondegenerate Companion

The Astrophysical Journal, 2023
Of the more than 3000 radio pulsars currently known, only ∼300 are in binary systems, and only five of these consist of young pulsars with massive nondegenerate companions.

The X-Ray Radiation Mechanism of the Compact (Neutron) Binary Stars [PDF]

Symposium - International Astronomical Union, 1987
Usually we think a X-ray source may be a compact(neutron) binary star on which the X-ray radiation might be generated by gravitational acceleration for the particles coming from the primary and going along magnetic field lines of the compact star to the poles. But, in the past, people don't consider well the problem of particle acceleration.
