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…

ESO Expanding Horizon White Paper: Revealing the properties of matter at supranuclear densities with gravitational waves

Tim Dietrich, Tanja Hinderer, Micaela Oertel +40

Understanding dense matter under extreme conditions is one of the most fundamental puzzles in modern physics. Complex interactions give rise to emergent, collective phenomena. Whil…

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…

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…

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…
