Self-Consistent Simulations of the Bar-mode Instability in Rotating Quasi-Stable Neutron Stars

Dr. Terrence Pierre Jacques
West Virginia University

Rapidly rotating neutron stars (NSs) formed from core-collapse supernovae serve as excellent astrophysical laboratories for probing their equation of state (EoS) and internal structure. As these stars cool and contract, their spin angular momentum may increase, making them susceptible to the dynamical bar-mode instability. Once this instability sets in, these stars experience a redistribution of matter and angular momentum, producing gravitational waves that may be detectable by future observatories.

In this talk, I will describe the numerical techniques used to model these quasi-stable NS configurations and demonstrate how gravitational wave signals produced from simulations can be used to constrain the NS EoS.
