Abstract / Description:We present results of the timing observations of the 143 ms pulsar PSR J0538+2817 that provide a proper-motion measurement clearly showing an association of the pulsar with the supernova remnant S147. We measure a proper motion of 67(-22)(+48) mas yr(-1), implying a transverse velocity of upsilon = 385(-130)(+260) km s(-1). We derive an age of the pulsar and S147 of only 30 +/- 4 kyr, which is a factor of 20 times less than the pulsar's characteristic age of tau(c) = 620 kyr. This age implies an initial spin period of P-0 = 139 ms, close to the present pulse period and a factor of several larger than what is usually inferred for birth periods. Implications for recent X-ray detections of this pulsar are discussed.
