We report on a timing analysis of archival observations of the Anomalous X– ray Pulsar 1RXS J170849.0–400910 made with the RXTE Proportional Counter Array. We detect a new large glitch (∆ν/ν ' 3× 10−6) which occurred between 2001 March 27 and 2001 May 6, with an associated large increase in the spin– down rate (∆ν̇/ν̇ ' 0.3). The short time (1.5 yrs) elapsed from the previously detected glitch and the large amplitude of the new spin–up place this source among the most frequent glitchers, with…

The anomalous X-ray pulsars (AXPs) represent a growing class of neutron stars discovered at X-ray energies. While the nature of their multi-wavelength emission mechanism is still under debate,
Superfluid spin up and pulsar glitch recovery
When a massive star comes to the end of its life, it explodes in a supernova, leaving behind a compact remnant known as a neutron star. The core density of a neutron star exceeds that of terrestrial
Improved post-processing in searches for continuous gravitational waves and a model for transient continuous gravitational wave emission from neutron star glitches
Gravitational waves (GW) are tiny oscillations in the fabric of space-time, first hypothesised within the framework of Einstein’s General theory of Relativity (GR) a little more than 100 years ago.
Gravitational wave transient signal emission via Ekman pumping in neutron stars during post-glitch relaxation phase
Glitches in the rotational frequency of a spinning neutron star could be promising sources of gravitational wave signals lasting between a few microseconds to a few weeks. The emitted signals and
Effect of entrainment on stress and pulsar glitches in stratified neutron star crust
The buildup of the stress whose relaxation is presumed to account for pulsar frequency glitches can be attributed to various mechanisms, of which the most efficient involve differential rotation of
Gravitational radiation from pulsar glitches
The nonaxisymmetric Ekman flow excited inside a neutron star following a rotational glitch is calculated analytically including stratification and compressibility. For the largest glitches, the
Physics of Neutron Star Crusts
This review summarizes the progress, which has been achieved over the last few years, in modeling neutron star crusts, both at the microscopic and macroscopic levels.
