Oscillations of Dissipative Neutron Stars: The Impact of Hyperonic Reaction Rates
Suprovo Ghosh, Alexander Haber, Nils Andersson +1
Tidal excitations of stellar oscillation modes during binary neutron-star inspirals offer a powerful probe of the composition of dense matter at supranuclear densities. Chemical eq…
Dynamical tidal response of neutron stars via scattering amplitudes
M. V. S. Saketh, Suprovo Ghosh, Nils Andersson
A key challenge of gravitational-wave physics is distinguishing the nature of compact objects in binary coalescences, in particular whether they are black holes or neutron stars. N…
The tidal response of a relativistic star
Nils Andersson, Rhys Counsell, Fabian Gittins +1
We develop a fully relativistic approach for determining the response of a compact star to a time/frequency dependent (tidal) environment. The strategy involves matching the soluti…
Dynamical neutron-star tides: The signature of a mode resonance
P. Pnigouras, N. Andersson, F. Gittins +1
Motivated by future opportunities in gravitational-wave astronomy and the ongoing effort to constrain physics under extreme conditions, we consider the signature of individual mode…
A post-Newtonian approach to neutron star oscillations
Shanshan Yin, Nils Andersson, Fabian Gittins
Next-generation gravitational-wave detectors are expected to constrain the properties of extreme density matter via observations of static and dynamical tides in binary neutron sta…
Interface modes in inspiralling neutron stars: A gravitational-wave probe of first-order phase transitions
A. R. Counsell, F. Gittins, N. Andersson +1
At the extreme densities in neutron stars, a phase transition to deconfined quark matter is anticipated. Yet masses, radii and tidal deformabilities offer only indirect measures of…
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…
Perturbation theory for post-Newtonian neutron stars
Fabian Gittins, Nils Andersson, Shanshan Yin
Neutron stars are compact, relativistic bodies that host several extremes of modern physics. An exciting development in recent years has been the opportunity to probe this exotic p…
Neutron star g-modes in the relativistic Cowling approximation
Rhys Counsell, Fabian Gittins, Nils Andersson +1
Mature neutron stars are expected to exhibit gravity g-modes due to stratification caused by a varying matter composition in the high-density core. By employing the BSk equation of…
Problematic systematics in neutron-star merger simulations
F. Gittins, R. Matur, N. Andersson +1
Next-generation gravitational-wave instruments are expected to constrain the equation of state of dense nuclear matter by observing binaries involving neutron stars. We highlight a…
Neutron-star seismology with realistic, finite-temperature nuclear matter
Fabian Gittins, Nils Andersson
The oscillation spectrum of a neutron star is notably rich and intrinsically dependent on the equation of state of nuclear matter. With recent advancements in gravitational-wave an…
