Orthogonal pulsars as a key test for pulsar evolution [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT At present, there is no direct information about evolution of inclination angle χ between magnetic and rotational axes in radio pulsars. As to theoretical models of pulsar evolution, they predict both the alignment, i.e. evolution of inclination angle χ to 0°, and its counter-alignment, i.e. evolution to 90°.

ПЕРВЫЕ РЕЗУЛЬТАТЫ ДЕКАМЕТРОВОГО ОБЗОРА СЕВЕРНОГО НЕБА. РЕДЕТЕКТИРОВАНИЕ ИЗВЕСТНЫХ ПУЛЬСАРОВ
Odessa Astronomical Publications, 2011 At the UTR-2 radio telescope the survey of northern sky is being conducted with aim to search for pulsars and transients. In the first stage the detection of a complete list of known pulsars with parameters DM -3, period more than 0.1 s and declination ...

Brazilian Journal of Physics, 2013 The high-energy sources known as anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are well explained as magnetars: isolated neutron stars powered by their own magnetic energy. After explaining why it is generally believed that the traditional energy sources at work in other neutron stars (accretion, rotation, residual heat) cannot ...

Gamma-ray emission from millisecond pulsars - an Outergap perspective [PDF]
Journal of Astronomy and Space Sciences, 2013 In this review paper we explain the following gamma-ray emission features from the millisecond pulsars. (1) Why is the dipolar field of millisecond pulsars so weak but the magnetic pair creation process may still be able to control the size of the ...

Spin Equilibrium of Rapidly Spinning Neutron Stars via Transient Accretion
Galaxies, 2023 The concept of spin equilibrium due to an interaction between the stellar magnetosphere and a thin, Keplerian accretion disk, and a well-known formula of the corresponding equilibrium spin frequency, provide a key understanding of spin evolution and the ...

Gravity Tests with Radio Pulsars
Universe, 2020 The discovery of the first binary pulsar in 1974 has opened up a completely new field of experimental gravity. In numerous important ways, pulsars have taken precision gravity tests quantitatively and qualitatively beyond the weak-field slow-motion ...

Pulsar Electrodynamics — Pulsars and Puzzlers — [PDF]
International Astronomical Union Colloquium, 1996 AbstractA gedanken experiment presented here provides basic understanding of how the pulsar magnetosphere operates. We discuss current issues about the electric-field acceleration along magnetic field lines and subsequent pair creation, and also about the pulsar wind problem.

Radio pulsar binaries in globular clusters: their orbital eccentricities and stellar interactions
, 2009 High sensitivity searches of globular clusters (GC) for radio pulsars by improved pulsar search algorithms and sustained pulsar timing observations have so far yielded some 140 pulsars in more than two dozen GCs.
