Description

Recent X-ray observations have revealed the existence of oscillations during the X-ray bursts of two accreting neutron stars. One possible explanation is that these represent r-mode oscillations. In this talk I explore the r-mode hypothesis, showing that it allows us to place a constraint on the relationship between mass and radius for these two stars. I also discuss what the observations tell us about the strength of dissipative processes within the stars, again adopting the r-mode hypothesis. I conclude by describing the significance of these considerations for gravitational wave searches.
