Simulating pulsar glitches: an N-body solver for superfluid vortex motion in two dimensions

Autor: Andrew Melatos, Brynmor Haskell, G. Howitt

Publikováno v: Monthly Notices of the Royal Astronomical Society. 498:320-331

A rotating superfluid forms an array of quantized vortex lines which determine its angular velocity. The spasmodic evolution of the array under the influence of deceleration, dissipation, and pinning forces is thought to be responsible for the phenom

A class of optical transients known as Luminous Red Novae (LRNe) have recently been associated with mass ejections from binary stars undergoing common-envelope evolution. We use the population synthesis code COMPAS to explore the impact of a range of

An updated glitch rate law inferred from radio pulsars

Autor: M Millhouse, A Melatos, G Howitt, J B Carlin, L Dunn, G Ashton

Radio pulsar glitches probe far-from-equilibrium processes involving stress accumulation and relaxation in neutron star interiors. Previous studies of glitch rates have focused on individual pulsars with as many recorded glitches as possible. In this

Anti-glitches in accreting pulsars from superfluid vortex avalanches

Autor: G Howitt, A Melatos

Three sudden spin-down events, termed `anti-glitches', were recently discovered in the accreting pulsar NGC 300 ULX-1 by the \textit{Neutron Star Interior Composition Explorer} (NICER) mission. Unlike previous anti-glitches detected in decelerating m

Common envelope episodes that lead to double neutron star formation

Autor: Serena Vinciguerra, Coenraad J. Neijssel, G. Howitt, Ilya Mandel, Floor S. Broekgaarden, Stephen Justham, Alejandro Vigna-Gómez, Morgan MacLeod, Selma E. de Mink

Close double neutron stars have been observed as Galactic radio pulsars, while their mergers have been detected as gamma-ray bursts and gravitational-wave sources. They are believed to have experienced at least one common-envelope episode during thei
