The Crab Pulsar, Radius Is a Neutron Star

Question 66

Multiple Choice

The Crab Pulsar, The Crab Pulsar, radius is a neutron star located in the Crab Nebula.The rotation of the Crab Pulsar is currently approximately 30 rotations per second,or 60 rad/s.The rotation rate of the star,however,is decreasing such that each year the rotation period increases by 10<sup>-5</sup> s.Estimate the amount of energy the pulsar looses each year. A) 4 * 10<sup>31</sup> J B) 2 * 10<sup>35</sup> J C) 1 * 10<sup>39</sup> J D) 6 * 10<sup>42</sup> J radius The Crab Pulsar, radius is a neutron star located in the Crab Nebula.The rotation of the Crab Pulsar is currently approximately 30 rotations per second,or 60 rad/s.The rotation rate of the star,however,is decreasing such that each year the rotation period increases by 10<sup>-5</sup> s.Estimate the amount of energy the pulsar looses each year.
