A binary pulsar in a 53-minute orbit. [PDF]

open access: yesNature, 2023
PSR J1953+1844 (M71E) has an orbital period of 53.3 minutes and a companion with a mass of 0.07  M _⊙, making it a bridging object between redbacks and black widows in the evolutionary track. Spider pulsars are neutron stars that have a companion star in

Modulated Gamma-ray emission from compact millisecond pulsar binary systems [PDF]

open access: bronze, 2013
A significant amount of the millisecond pulsars has been discovered within binary systems. In several such binary systems the masses of the companion stars have been derived allowing to distinguish two classes of objects, called the Black Widow and the ...

A timing formula for main-sequence star binary pulsars [PDF]

open access: bronze, 1997
In binary radio pulsars with a main-sequence star companion, the spin-induced quadrupole moment of the companion gives rise to a precession of the binary orbit.

A Massive Pulsar in a Compact Relativistic Binary [PDF]

open access: yesScience, 2013
Introduction Neutron stars with masses above 1.8 solar masses (M☉), possess extreme gravitational fields, which may give rise to phenomena outside general relativity.

Overcoming the Challenges of Transmural Durable Lesions With PFA-Impact of Electrode Design and Contact Assessment. [PDF]

open access: yesPacing Clin Electrophysiol
Abstract Electrode design and reliable contact assessment are critical for creating durable pulsed field ablation (PFA) lesions to treat atrial fibrillation while minimizing collateral damage. This review introduces a novel “map‐and‐ablate” PFA catheter featuring flat electrodes, thermal contact assessment, and fully customizable electrode selection ...

Proton Acceleration with Relativistic Electromagnetic Shock. [PDF]

open access: yesAdv Sci (Weinh)
New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

1974: the discovery of the first binary pulsar [PDF]

open access: yes, 2015
The 1974 discovery, by Russell A. Hulse and Joseph H. Taylor, of the first binary pulsar PSR B1913+16, opened up new possibilities for the study of relativistic gravity.

A NICER View of the Nearest and Brightest Millisecond Pulsar: PSR J0437–4715 [PDF]

open access: yesThe Astrophysical Journal Letters
We report Bayesian inference of the mass, radius, and hot X-ray emitting region properties—using data from the Neutron Star Interior Composition ExploreR (NICER)—for the brightest rotation-powered millisecond X-ray pulsar, PSR J0437−4715. Our modeling is

SOME EVOLUTIONARY ASPECTS OF THE BINARY STELLAR SYSTEMS CONTAINING NEUTRON STAR

open access: yesOdessa Astronomical Publications, 2012
The obvious lack of the binary stellar systems that contain neutron stars (NS) is observed at present. Partly it is caused by the fact that it is very difficult to detect neutron star in a binary system if this relativistic component does not manifest ...

Binary and Millisecond Pulsars

open access: yesLiving Reviews in Relativity, 2008
We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar ...
