Description
Thanks to their rapid rotation, millisecond pulsars are one of the most important sources to search for signatures of r-mode oscillations, which may be used to constrain the composition of neutron stars. This requires measurements or bounds on the surface temperatures of these faint objects. e-ROSITA, onboard Spektrum-Roentgen-Gamma satellite, recently completed the most detailed X-ray survey of the southern sky. We searched for X-ray counterparts of all the millisecond pulsars, spinning at a rate greater than 300 Hz and within 2 kpc, detected in this survey and used the measured soft X-ray fluxes, to put new limits on the amplitude of r-mode oscillations. Our results already give us some promising constraints on the r-mode amplitudes. In this poster we present these results and provide the list of sources for which further deep followup observations may result in important constraints.
