Abstract
We report the discovery of a 143 ms pulsar, PSR J05382817, in the supernova remnant S147 (G180.01.7). The pulsar is located 40 west of the center of S147, well within its evolved, roughly circular radio structure. An upper limit to the pulsar's age of 6 10 5 yr is consistent with the age of the remnant, estimated to be 1(8 10 4 )-(2 10 5 ) yr. A dispersion measure-derived distance to PSR J05382817 is 11.8 kpc, in reasonable agreement with a 0.8 -1.6 kpc distance estimate for S147. These data provide sufficient evidence to hypothesize that the two objects are physically related and form a new association between a radio pulsar and an old supernova remnant.
