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

Heat propagation in rotating relativistic bodies
Lorenzo Gavassino, Marco Antonelli
We investigate heat propagation in rigidly rotating bodies within the theory of general relativity. Using a first-order gradient expansion, we derive a universal partial differenti…
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…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
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…
Anisotropic electron transport in the nuclear pasta phase
Mateus R. Pelicer, Marco Antonelli, Débora P. Menezes +1
The presence of nuclear pasta is expected to modify the transport properties in the mantle of neutron stars. The non-spherical geometry of the pasta nuclear clusters leads to aniso…
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…
Relativistic Liquids: GENERIC or EIT?
Lorenzo Gavassino, Marco Antonelli
We study the GENERIC hydrodynamic theory for relativistic liquids formulated by Ottinger and collaborators. We use the maximum entropy principle to derive its conditions for linear…
Symmetric-hyperbolic quasi-hydrodynamics
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
We set up a general framework for systematically building and classifying, in the linear regime, causal and stable dissipative hydrodynamic theories that, alongside with the usual…
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…
Simulating bulk viscosity in neutron stars. II. Evolution in spherical symmetry
Giovanni Camelio, Lorenzo Gavassino, Marco Antonelli +2
Out-of-equilibrium reactions between different particle species are the main processes contributing to bulk viscosity in neutron stars. In this work, we numerically compare three d…
Simulating bulk viscosity in neutron stars. I. Formalism
Giovanni Camelio, Lorenzo Gavassino, Marco Antonelli +2
The faithful inclusion of the effects of bulk viscosity induced by the presence of chemical reactions is an important issue for simulations of core-collapse supernovae, binary neut…
Extending Israel and Stewart hydrodynamics to relativistic superfluids via Carter's multifluid approach
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
We construct a relativistic model for bulk viscosity and heat conduction in a superfluid. Building on the principles of Unified Extended Irreversible Thermodynamics, the model is d…
Unified Extended Irreversible Thermodynamics and the stability of relativistic theories for dissipation
Lorenzo Gavassino, Marco Antonelli
In a relativistic context, the main purpose of Extended Irreversible Thermodynamics (EIT) is to generalize the principles of non-equilibrium thermodynamics to the domain of fluid d…
Thermodynamic stability implies causality
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
The stability conditions of a relativistic hydrodynamic theory can be derived directly from the requirement that the entropy should be maximised in equilibrium. Here we use a simpl…
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…
Multifluid Modelling of Relativistic Radiation Hydrodynamics
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
The formulation of a universal theory for bulk viscosity and heat conduction represents a theoretical challenge for our understanding of relativistic fluid dynamics. Recently, it h…
When the entropy has no maximum: A new perspective on the instability of the first-order theories of dissipation
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
The first-order relativistic fluid theories of dissipation proposed by Eckart and Landau-Lifshitz have been proved to be unstable. They admit solutions which start in proximity of…
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…
Bulk viscosity in relativistic fluids: from thermodynamics to hydrodynamics
Lorenzo Gavassino, Marco Antonelli, Brynmor Haskell
