The crab pulsar winds down. theoretical models indicate that the age of a pulsar is about p/(2r), where p is the pulsar’s period, and r is the rate that the pulsar slows with time. the pulsar in the crab nebula is pulsing 30 times a second (so p = 0.0333 seconds). but the time interval between pulses is actually growing longer by 4.2x10-13seconds with each passing second (so r = 4.2x10-13 seconds per second). knowing this, how old is the crab pulsar? how does your age compare to the true age of the pulsar, which was born in the supernova observed in a. d. 1054?
