Question

Consider a neutron star with a mass equal to 0.9 times the mass of the Sun, a radius of 15 km, and a rotation period of 1.3 s. What is the speed of a point on the equator of this neutron star? What is gg at the surface of this neutron star? A stationary 1.0 kg mass has a weight of 9.8 N on Earth. What would be its weight on the neutron star? How many revolutions per second are made by a satellite orbiting 1.0 km above the surface?

Answer #1

See problem 52 in Chapter 13 of the 3rd Edition of Knight for
some background information about neutron stars. Consider a neutron
star with a mass equal to 0.9 times the mass of the Sun, a radius
of 15 km, and a rotation period of 1.3 s. What is the speed of a
point on the equator of this neutron star? What is gg at
the surface of this neutron star? A stationary 1.0 kg mass has a
weight of...

See problem 52 in Chapter 13 of the 3rd Edition of Knight for
some background information about neutron stars. Consider a neutron
star with a mass equal to 0.7 times the mass of the Sun, a radius
of 14.2 km, and a rotation period of 1 s. What is the speed of a
point on the equator of this neutron star?
What is gg at the surface of this neutron star?

Large stars can explode as they finish burning their nuclear
fuel, causing a supernova. The explosion blows away the outer
layers of the star. According to Newton’s third law, the forces
that push the outer layers away have reaction forces that are
inwardly directed on the core of the star. These forces compress
the core and can cause the core to undergo a gravitational
collapse. The gravitational forces keep pulling all the matter
together tighter and tighter, crushing atoms out...

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? Assume that the star is a uniform
sphere at all times and that the lost mass carries off no angular
momentum.

Suppose a star the size of our Sun, but with mass 5.0 times as
great, were rotating at a speed of 1.0 revolution every 15 days. If
it were to undergo gravitational collapse to a neutron star of
radius 14 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
Part A) No angular momentum
Part B) its proportional share three-quarters of the initial...

A typical neutron star may have a mass equal to that of the Sun
but a radius of only 12 km. (a) What is the gravitational
acceleration at the surface of such a star? (b) How fast would an
object be moving if it fell from rest through a distance of 1.5 m
on such a star? (Assume the star does not rotate.)

A binary pulsar is a system of two neutron stars of equal mass
(each about 1.4 times the mass of the sun and a radius of 10km). A
particular binary pulsar has two neutron stars orbiting around
their center of mass, and separated by a (center to center)
distance of d= 7.0*10^8m. Assume the orbit is circular.
a) Calculate the orbital speed of the stars in meters/second.
b) Calculate the magnitude of the centripetal acceleration of one
of the stars...

Assume a neutron star has a mass of about 1.2 times the mass of
the Sun and a radius of 7 kilometers.
a) Calculate the average density of a neutron star, in kilograms
per cubic centimeter.
b) If the escape speed is V2esc=2GM/R, work out the formula for
the radius of the Event Horizon around a Black Hole of mass M.
c) Assume the Even Horizon is the size of the Black Hole. What
is the density of a Black...

Suppose a star the size of our Sun, but with mass 8.0 times as
great, were rotating at a speed of 1.0 revolution every 8.0 days.
If it were to undergo gravitational collapse to a neutron star of
radius 11 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
a) no angular momentum
b)its proportional share three-quarters of the initial angular
momentum
Express...

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....
