Description

Studying isolated asymmetric neutron stars via continuous gravitational waves has become a new approach to understanding neutron star physics, given improvements in detector sensitivity and the upcoming next-generation detectors like the Einstein Telescope, which will make detection of these signals feasible in the near future. In our work, we investigate whether corrections to the gravitational wave phase beyond the simple rotating ellipsoid model affect results and how they would bias constraints on our detections, thereby improving our search pipelines. These phase contributions can arise from any physical effects such as spin wandering, timing noise and lensing of continuous waves.
