[17.04] X-ray Signatures of Gravitational Radiation from LMXB Neutron Stars

R. Wagoner (Stanford Univ., KIPAC)

The coupled evolution of the spin frequency, core temperature, surface luminosity, and r-mode amplitude of an accreting neutron star is calculated. We focus on those conditions that can produce persistent gravitational radiation from the r-mode. During X-ray quiescent phases of transient LMXBs, one may be able to identify the constant contribution of the gravitational wave emission to the spindown rate. Another signature is the excess quiescent luminosity produced by the r-mode contribution to the heating. X-ray spectra of isolated neutron stars can help to constrain the large uncertainties in the superfluid transition temperatures of the neutrons and protons. The superfluid transition temperature of the hyperons can also play a critical role in the damping of the r-mode.
