When a neutron star is formed it is rotating very rapidly.

a) What are these objects typically called and how do we find them?

b) The first one of these objects found was called a LGM. What does that stand for and why were they called that?

Answer #1

A rotating neutron star is called a pulsar, due to its rotation its emmits electromagnetic radiation at regular intervals. If the beam is pointed towards earth then we can receive the signal and that's how we confirm the existence of a pulsar.

In 1967, when the first time humans observed the pulses from space, they thought it's from some extra terrestrial species. Later on research and receiving more such signals they realized that it is a natural phenomenon. The first pulsar was named as LGM-1 that stands for 'little green man' because it was originally considered to be an alien.

Astronomers detect stars that are rotating extremely rapidly, known as neutron stars. A neutron star is believed to form from the inner core of a larder star that collapsed, under its own gravitation, to a star of very small radius and very high density. Before collapse, suppose the ore of such a star is the size of our Sun (R = 7105km)with mass 2.0 times as great as the Sun, and is rotating at a frequency of 1.0 revolution every...

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 = 0.0833 s that is increasing at the rate of 1.89 x 10-6 s/y. (a) What is the pulsar's angular acceleration α? (b) If α...

A pulsar is a rapidly rotating neutron star that emits radio pulses with precise synchronization, there being one such pulse for each rotation of the star. The period T of rotation is found by measuring the time between pulses. At present, the pulsar in the central region of the Crab nebula has a period of rotation of T = 0.16000000 s, and this is observed to be increasing at the rate of 0.00000943 s/y. What is the angular velocity of...

Occasionally, a rotating neutron star undergoes a sudden and unexpected speedup called a glitch. One explanation is that a glitch occurs when the crust of the neutron star settles slightly, decreasing the moment of inertia about the rotation axis. A neutron star with angular speed v = 70.4 rad/s underwent such a glitch in October 1975 that increased its angular speed to w = w0 + ?w, where ?w/w0 = 2.01 x 10-6 . What is the moment of inertia...

One particular neutron star has a mass equal to 3.00 times the mass of the sun. You may consider this neutron star to be a sphere with a uniform density of 3.30×1017 kg/m3 !! ......compare that to the density of lead for example, at 1×104 kg/m3 . (A neutron star is created when a massive star runs out of hydrogen fuel and collapses at the end of its life. The neutron star is a very dense and spins rapidly). If...

During the helium flash a star generates a very large amount of energy and pressure over a very small time. What does this increase in pressure accomplish within the star? When a low mass star first develops an inert carbon core what elements (if any) are still burned within the star? What is the final element generated in the core of high mass stars? (Hint: fusion of this element releases no energy) Where are the heaviest elements formed? (All elements...

2-Consider very specific products. that you typically purchase. a) When should the government regulate prices in specific product markets and when should we let supply & demand do their job? (Don't get bogged down in "big issues" such as income distribution or product safety or macro issues) Think of a product like skirts or blouses. Should the government give out free skirts or blouses to all, or should they be sold in stores? Should the price be kept down by...
