Variable Magellanic HMXB Sources versus Variable ULX Sources: Nothing to Brag about the ULX Sources

Galaxies, 2020
We carry out a meta-analysis of ultraluminous X-ray (ULX) sources that show large variabilities (by factors of >10) between their highest and lowest emission states in the X-ray energy range of 0.3–10 keV.

Fifty years of pulsar candidate selection: from simple filters to a new principled real-time classification approach [PDF]

Monthly notices of the Royal Astronomical Society, 2016
Improving survey specifications are causing an exponential rise in pulsar candidate numbers and data volumes. We study the candidate filters used to mitigate these problems during the past fifty years.

Populating the Galaxy with pulsars I: stellar & binary evolution

, 2008
The computation of theoretical pulsar populations has been a major component of pulsar studies since the 1970s. However, the majority of pulsar population synthesis has only regarded isolated pulsar evolution.

GMRT Discovery of A Millisecond Pulsar in a Very Eccentric Binary System [PDF]

, 2004
We report the discovery of the binary millisecond pulsar J0514-4002A, which is the first known pulsar in the globular cluster NGC 1851 and the first pulsar discovered using the Giant Metrewave Radio Telescope (GMRT). The pulsar has a rotational period of

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 ...

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.

A periodically active pulsar giving insight into magnetospheric physics [PDF]

, 2006
PSR B1931+24 (J1933+2421) behaves as an ordinary isolated radio pulsar during active phases that are 5-10 days long. However, the radio emission switches off in less than 10 seconds and remains undetectable for the next 25-35 days, then it switches on ...

Radio emission from a pulsar’s magnetic pole revealed by general relativity [PDF]

Science, 2019
General relativity reveals pulsar beams Pulsars are rotating neutron stars that emit beams of radio waves along their magnetic poles, seen as regular pulses if the beam points toward Earth. Desvignes et al.
