Probing Neutron Star Interiors and the Properties of Cold Ultra-dense Matter with the SKAO
Avishek Basu, Vanessa Graber, Marcus E. Lower +19
Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutr…
Probing neutron star interiors and the properties of cold ultra-dense matter with the SKAO
Avishek Basu, Vanessa Graber, Marcus E. Lower +19
Matter inside neutron stars is compressed to densities several times greater than nuclear saturation density, while maintaining low temperatures and large asymmetries between neutr…
Gravitational pulsars: correlations between the electromagnetic and the continuous gravitational wave signal
Marco Antonelli, Avishek Basu, Brynmor Haskell
Neutron stars emitting continuous gravitational waves may be regarded as gravitational pulsars, in the sense that it could be possible to track the evolution of their rotational pe…
Insights into the physics of neutron star interiors from pulsar glitches
Marco Antonelli, Alessandro Montoli, Pierre Pizzochero
The presence of superfluid phases in the interior of a neutron star affects its dynamics, as neutrons can flow relative to the non-superfluid (normal) components of the star with l…
Continuous gravitational wave emission from neutron stars with pinned superfluids in the core
Brynmor Haskell, Marco Antonelli, Pierre Pizzochero
We investigate the effect of a pinned superfluid component on the gravitational wave emission of a rotating neutron star. Pinning of superfluid vortices to the flux-tubes in the ou…
Stochastic processes for pulsar timing noise: fluctuations in the internal and external torques
Marco Antonelli, Avishek Basu, Brynmor Haskell
Young pulsars deviate from a perfectly regular spin-down by two non-deterministic phenomena: impulsive glitches and timing noise. Both phenomena are interesting per se, and may pro…
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…
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…
Bayesian estimate of the superfluid moments of inertia from the 2016 glitch in the Vela pulsar
Alessandro Montoli, Marco Antonelli, Fabio Magistrelli +1
The observation of the first pulse-to-pulse glitch in the Vela pulsar opens a new window on the internal dynamics of neutron stars. We study the minimal three-component model for p…
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…
Core and crust contributions in overshooting glitches: the Vela pulsar 2016 glitch
Pierre Pizzochero, Alessandro Montoli, Marco Antonelli
During the spin-up phase of a large pulsar glitch - a sudden decrease of the rotational period of a neutron star - the angular velocity of the star may overshoot, namely reach valu…
Hydrodynamical instabilities in superfluid neutron stars with background flows between the components
Vadym Khomenko, Marco Antonelli, Brynmor Haskell
The interiors of mature neutron stars are expected to be superfluid. Superfluidity of matter on the microscopic scale can have a number of large scale, potentially observable conse…
Incompressible analytical models for spinning-down pulsars
Elia Giliberti, Marco Antonelli, Gabriele Cambiotti +1
We study a class of Newtonian models for the deformations of non-magnetized neutron stars during their spin-down. The models have all an analytical solution, and thus allow to unde…
Modelling strains and stresses in continuously stratified rotating neutron stars
Elia Giliberti, Gabriele Cambiotti, Marco Antonelli +1
We introduce a Newtonian model for the deformations of a compressible, autogravitating, and continuously stratified neutron star. The present framework can be applied to a number o…
The role of mass, equation of state and superfluid reservoir in large pulsar glitches
Alessandro Montoli, Marco Antonelli, Pierre Pizzochero
Observations of pulsar glitches may provide insights on the internal physics of neutron stars and recent studies show how it is in principle possible to constrain pulsar masses wit…
Core and crust contributions in pulsar glitches: constraints from the slow rise of the largest glitch observed in the Crab pulsar
Brynmor Haskell, Vadym Khomenko, Marco Antonelli +1
Pulsar glitches are attributed to the sudden re-coupling of very weakly coupled large scale superfluid components in the neutron star interior. This process leads to rapid exchange…
Effects of general relativity on glitch amplitudes and pulsar mass upper bounds
M. Antonelli, A. Montoli, P. M. Pizzochero
Pinning of vortex lines in the inner crust of a spinning neutron star may be the mechanism that enhances the differential rotation of the internal neutron superfluid, making it pos…
Pulsar rotation with superfluid entrainment
Marco Antonelli, Pierre Pizzochero
Large pulsar glitches (like the ones detected in the Vela) are though to be a consequence of the superfluid component present in the interior of mature neutron stars. However stron…
Constraints on pulsar masses from the maximum observed glitch
Pierre Pizzochero, Marco Antonelli, Brynmor Haskell +1
Pulsar glitches, sudden jumps in frequency in otherwise steadily spinning down radio pulsars, offer a unique glimpse into the superfluid interior of neutron stars. The exact trigge…
