a) In a little over 5 billion years, our star will slough off ~20% of its mass and collapse to a white dwarf star of radius 8,000 km. We will model it as a sphere. What will its angular momentum be in terms of its current angular momentum? What will its rotation period be in terms of its current period?

b) (12 points) What will its rotational kinetic energy be in terms of its current rotational kinetic energy?

In a little over 5 billion years, our Sun will collapse to a white dwarf approximately 16,000 km in diameter. (Ignore the fact that the Sun will lose mass as it ages.) (a) What will our Sun’s angular momentum and rotation rate be as a white dwarf? (Express your answers as multiples of its present-day values.) (b) Compared to its present value, will the Sun’s rotational kinetic energy increase, decrease, or stay the same when it becomes a white dwarf?...

Suppose a star the size of our Sun (r=7.0*105 km), but with mass 6.0 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 10 km, losing 2/3 of its mass in the process, what would its rotation period be in μs? Assume the star is a uniform sphere at all times. Assume also that the thrown-off mass carries off no angular momentum....

The star Tau Ceti's mass is 1.6 ✕ 1030 kg, its radius is 5.5 ✕ 105 km, and it has a rotational period of approximately 34 days. If Tau Ceti should collapse into a white dwarf of radius 9.7 ✕ 103 km, what would its period (in s) be if no mass were ejected and a sphere of uniform density can model Tau Ceti both before and after? _______ s

Suppose a star the size of our Sun, but of mass 8.0 times as great, was rotating at a speed of 1.0 revolution every 21 days. If it were to undergo gravitational collapse to a neutron star of radius 20 km, losing three quarters of its mass in the process, what would its rotation speed be?

A white dwarf star (R = 0.0073 R⦿, M= 1.4 M⦿) goes over the Chandrasekhar limit and collapses to a neutron star (R=10 km). At that point the collapse stops. The collapse time is 0.1 seconds. A) Calculate the total amount of energy liberated from the star in the collapse. B) Estimate the luminosity (energy liberated/collapse time). C) If the white dwarf was originally spinning with a 1.3 day period, what would the period of the neutron star rotation be?

Neutron Star Physics Under some circumstances, an ordinary star can undergo gravitational collapse into an extremely dense object made mostly of neutrons. This type of star is called a "neutron star". A neutron star has a mass density roughly 1014 times larger than that of ordinary solid matter. Suppose we represent an ordinary star as a uniform solid rigid sphere, both before and after the collapse. The original star's initial radius is 7.0 x 105 km (comparable to the size...
