Astronomers use evidence of rapid rotation as identification of a neutron star. As you might imagine, if the mass of a star becomes condensed (collapsed star will have a smaller radius), its density increases. Imagine a star with a core the size of our sun 7 hundred thousand km and a mass 2x that our our sun. This star completes one revolution in 10 days. Should this star undergo gravitational collapse to a radius of 10 km, what will the rotational speed of this neutron star be in both rev/s and rad/s

PartA Constants Suppose a star the size of our Sun, but with mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 10 days. If it were to undergo gravitational collapse to a neutron star of radius 12 km, losing three-quarters of its mass in the process, what would its rotation speed be? Assume also that the thrown-off mass carries off either no angular momentum Express your answer using two significant figures. A2c rev/s Part B...

10. At the end of the Sun’s life it will use up the hydrogen and helium in its core and become a white dwarf. The Sun’s mass is 2.0 × 1030 kg, its radius is 7.0 × 105 km, and it has a rotational period of approximately 28 days. If the Sun should collapse into a white dwarf of radius 3.5 × 103 km, what would its period be if no mass were ejected and a sphere of uniform density...

Formation of a Neutron Star A star rotates with a period of 29 days about an axis through its center. The period is the time interval required for a point on the star's equator to make one complete revolution around the axis of rotation.
