Abstract
We report the observation of nine pulsars using the Lexan (100 A) band of the Extreme Ultraviolet Explorer scanning telescopes. The observations, none of which resulted in positive detections, are used to derive limits to the temperature of surface thermal radiation from the objects. We compare the temperature limits with predictions from neutron star cooling models. The NH I toward our targets limits our ability to establish rigorous limits needed to discriminate among the models. We also derive a limit to heating by magnetic monopole flux–catalyzed nucleon decay for the very old pulsar PSR J1455-3330, which is similar to the limit derived for PSR B1929+10 and 3 orders of magnitude larger than the limit for PSR J0437-4715.
