We model the quiescent luminosity of accreting neutron stars with several equation of states (EOSs), including the effect of pion condensation and superfluidity. As a consequence of comparison with the observations, we show that the results with Togashi EOS (the strong direct Urca process is forbidden) and TM1e EOS (mass at direct Urca process is $2.06\text{ }\text{ }{M}_{\ensuremath{\bigodot}}$) can explain the observations well by considering pion condensation and the effect of superfluidity… Expand

We observed SAX J1808.4-3658 (1808), the first accreting millisecond pulsar, in deep quiescence with XMM-Newton and (near simultaneously) Gemini-South. The X-ray spectrum of 1808 is similar to thatExpand
