Prospects for transient gravitational waves at r-mode frequencies associated with pulsar glitches

Understand

Glitches in pulsars are likely to trigger oscillation modes in the fluid interior of neutron stars.

• We examined these oscillations specifically at r-mode frequencies.
• The excited r-modes will emit gravitational waves and can have long damping time scales O(minutes - days).
• We use simple estimates of how much energy the glitch might put into the r-mode and assess the detectability of the emitted gravitational waves with future interferometers.
