A Timing Signature of Gravitational Radiation from LMXB Neutron Stars

The coupled evolution of the spin frequency, core temperature, 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 r‐mode contribution to the heating.
