Gravitational waves from glitch-induced -mode oscillations in quark and neutron stars
OH Wilson, WCG Ho - Physical Review D, 2024 - APS
Matter in compact stars is dense enough that transient events within the star could have
sufficiently high energies to produce detectable gravitational waves (GWs). These GWs …
