... Power output of the Crab pulsar •Power output of the Crab pulsar, in radio and X-rays, is about 6 x 1031 W (which is about 150,000 times the power output of our sun). Since the pulsar is out of nuclear fuel, where does all this energy come from ? • The angular speed of the pulsar, and so the rotati ...
