Neutron Stars - Thermal
A search for thermal emission from cooling neutron stars has yielded seven
objects. Their X-ray luminosities are shown as a function of age:
the Vela pulsar (asterisks); the three middle-aged pulsars PSR 0656+14,
Geminga and PSR 1055-52 (diamonds);
the X-ray point sources in the supernova remnants
RCW 103, Puppis A and PKS 1209-52 (small diamonds).
Upper limits are shown for the Crab pulsar and PSR 1509-58 (bullets).
For comparison the cooling curves for standard cooling for a medium
stiff equation of state and accelerated cooling due to the effects of
a Bose-Einstein condensate are shown.
The diagram shows the bolometric luminosities for these objects.
