The accreting millisecond pulsar SAX J1808.4‐3658 may be a transition object between accreting X‐ray binaries and millisecond radio pulsars. We have constrained the thermal radiation from its surface through XMM‐Newton X‐ray observations, providing strong evidence for neutrino cooling processes from the neutron star core. We have also undertaken simultaneous X‐ray and optical (Gemini) observations, shedding light on whether the strong heating of the companion star in quiescence may be due to X‐ray irradiation, or to a radio pulsar turning on when accretion stops.
