LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
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…
Tidal heating in binary inspiral of strange quark stars
Suprovo Ghosh, José Luis Hernández, Bikram Keshari Pradhan +3
We investigate tidal heating associated with the binary inspiral of strange quark stars and its impact on the resulting gravitational wave signal. Tidal heating during the merger o…
Tidal dissipation in binary neutron star inspirals from hyperon bulk viscosity: Phase modeling and parameter estimation bias
Suprovo Ghosh, Samanwaya Mukherjee, Sukanta Bose +1
During the inspiral of a binary neutron star, viscous processes in the neutron star matter can damp out the tidal energy induced by its companion and convert it to thermal energy.…
