Axion condensates in neutron stars and radial oscillation modes
Antonio Gómez-Bañón, Pantelis Pnigouras, José A. Pons
Light QCD axions, introduced to solve the strong CP problem, may form condensates inside neutron stars, giving rise to a novel ground state of dense matter. We investigate how such…
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…
Nonlinear coupling between magnetar QPOs
Pantelis Pnigouras, Samuel K. Lander
The quasi-periodic oscillations (QPOs) observed in the tails of magnetar giant -ray flares have long been interpreted as normal oscillation modes of these stars. However, most s…
