22. Measuring the crust-superfluid coupling time-scale for 105 UTMOST pulsars

Talk

Crust-superfluid coupling plays an important role in neutron star rotation, particularly with respect to timing noise and glitches. Here, we present new timing-noise-based estimates of the crust-superfluid coupling timescale $\tau$ for 105 radio pulsars in the UTMOST dataset, by Kalman filtering the pulse times of arrival. The 105 objects are selected because they favour a two-component,...

30. Constraining neutron star properties with current and future gravitational wave observations of glitching pulsars

Talk

Rapidly rotating pulsars are known to undergo spontaneous increases in their rotation frequency known as "glitches" which interrupt their normal spindown rate. While the precise mechanism is unknown, this process is believed to be due to an internal exchange of angular momentum. Such a process may cause the emission of gravitational waves across multiple frequency bands and timescales which...

23. Superfluid vorticity, Magnus mountains, and gravitational waves

Talk

Rotating neutron stars, if deformed away from axisymmetry, produce long-lived gravitational waves. One possible source for such “mountains” is a non-axisymmetric distribution of the neutron superfluid’s vorticity, sustained by vortex pinning to the star’s solid outer crust, or to the magnetic flux tubes in the core. The Magnus force generated distorts the star, giving what we term a “Magnus...
