A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio pulse for each rotation of the star. The period of rotation is found by measuring the time between pulses. Suppose a pulsar has a period of rotation of T=0.0478s that is increasing at the rate of 488 x 10-8 (a) What is the pulsar's angular acceleration a ? (b) is constant, how many years...
A pulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. We receive a radio pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. Suppose a pulsar has a period of rotation of T = 0.0890 s that is increasing at the rate of 1.59 Times 10^-7 s/y. (a) What is the pulsar's angular acceleration alpha? If alpha is...

One of the most studied objects in the night sky is the Crab nebula, the remains of a supernova explosion observed by the Chinese in 1054. In 1968 it was discovered that a pulsar-a rapidly rotating neutron star that emits a pulse of radio waves with each revolution-lies near the center of the Crab nebula. The period of this pulsar is 33 ms. What is the angular speed in rad/s of the Crab nebula pulsar?
6. • The Crab Nebula One of the most studied objects in the night sky is the Crab nebula, the remains of a supernova explosion observed by the Chinese in 1054. In 1968 it was discovered that a pulsar-a rapidly rotating neutron star that emits a pulse of radio waves with each revolution-lies near the center of the Crab nebula.

The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for quasars (these are extremely bright, compact and remote objects that emit up to a thousand times as much light as our entire galaxy). For that purpose the research group designed a radio-telescope that was built on the flat fields surrounding Cambridge in central England. This telescope did...
