Superfluid dynamics in neutron star crusts: the Iordanskii force and chemical gauge covariance
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
We present a geometrical derivation of the relativistic dynamics of the superfluid inner crust of a neutron star. The resulting model is analogous to the Hall-Vinen-Bekarevich-Khal…
Statistical estimates of the pulsar glitch activity
Alessandro Montoli, Marco Antonelli, Brynmor Haskell +1
A common way to calculate the glitch activity of a pulsar is an ordinary linear regression of the observed cumulative glitch history. This method however is likely to underestimate…
Axisymmetric models for neutron star merger remnants with realistic thermal and rotational profiles
Giovanni Camelio, Tim Dietrich, Stephan Rosswog +1
Merging neutron stars are expected to produce hot, metastable remnants in rapid differential rotation, which subsequently cool and evolve into rigidly rotating neutron stars or col…
Gravitational waves from mountains in newly born millisecond magnetars
Ankan Sur, Brynmor Haskell
In this paper we study the spin-evolution and gravitational-wave luminosity of a newly born millisecond magnetar, formed either after the collapse of a massive star or after the me…
Proper motion, spectra, and timing of PSR J1813-1749 using Chandra and NICER
Wynn C. G. Ho, Sebastien Guillot, P. M. Saz Parkinson +7
PSR J1813-1749 is one of the most energetic rotation-powered pulsars known, producing a pulsar wind nebula (PWN) and gamma-ray and TeV emission, but whose spin period is only measu…
Return of the Big Glitcher: NICER timing and glitches of PSR J0537-6910
Wynn C. G. Ho, Cristobal M. Espinoza, Zaven Arzoumanian +7
PSR J0537-6910, also known as the Big Glitcher, is the most prolific glitching pulsar known, and its spin-induced pulsations are only detectable in X-ray. We present results from a…
Simulating pulsar glitches: an -body solver for superfluid vortex motion in two dimensions
G. Howitt, A. Melatos, B. Haskell
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, dissi…
Turbulent, pinned superfluids in neutron stars and pulsar glitch recoveries
Brynmor Haskell, Danai Antonopoulou, Carlo Barenghi
Pulsar glitches offer an insight into the dynamics of superfluids in the high density interior of a neutron star. To model these phenomena, however, one needs to have an understand…
Magnetic fields in late-stage proto-neutron stars
S. K. Lander, P. Haensel, B. Haskell +2
We explore the thermal and magnetic-field structure of a late-stage proto-neutron star. We find the dominant contribution to the entropy in different regions of the star, from whic…
Superfluid vortex-mediated mutual friction in non-homogeneous neutron star interiors
Marco Antonelli, Brynmor Haskell
Understanding the average motion of a multitude of superfluid vortices in the interior of a neutron star is a key ingredient for most theories of pulsar glitches. In this paper we…
Magnetic field configurations in neutron stars from MHD simulations
Ankan Sur, Brynmor Haskell, Emily Kuhn
We have studied numerically the evolution of magnetic fields in barotropic neutron stars, by performing nonlinear magnetohydrodynamical simulations with the code PLUTO. For both in…
The effect of non-linear mutual friction on pulsar glitch sizes and rise times
Thomas Celora, Vadym Khomenko, Marco Antonelli +1
Observations of pulsar glitches have the potential to provide constraints on the dynamics of the high density interior of neutron stars. However, to do so, realistic glitch models…
A universal formula for the relativistic correction to the mutual friction coupling time-scale in neutron stars
Lorenzo Gavassino, Marco Antonelli, Pierre Pizzochero +1
Vortex-mediated mutual friction governs the coupling between the superfluid and normal components in neutron star interiors. By, for example, comparing precise timing observations…
