Question

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 in units of m/s^2.

c) If you were able to stand on the surface of a neutron star, what
would be the acceleration due to gravity? ( Give answer in Earth
g's, where 1 Earth g= 9.8 m/s^2)

Answer #1

neutron stars, such as the one at the center of the crab Nebula,
have about the same mass as our sun but a much smaller diameter. if
you weigh 690 N on the earth, what would be your weight on the
surface of a neutron star has the same mass our sun and a diameter
of 190. km? take the mass of the sun to be ms= 1.99x10^30 kg. the
gravitational constant to be G= 6.67x10^-11 N.m^2/kg^2. and the
acceleration...

Two stars M_1 and M_2 of equal mass make up a binary star
system. They move in a circular orbit that has its center at the
midpoint of the line that separates them. If M_1=M_2=5.45 sm (solar
mass), and the orbital period of each star is 2.70 days, find their
orbital speed. (The mass of the sun is 1.99x10^30kg).
Point fully awarded to correct answer with full break-down of
formulas that led to correct answer.

Neutron stars, such as the one at the center of the Crab Nebula,
have about the same mass as our sun but a much smaller diameter. If
you weigh 670 N on the earth, what would be your weight on the
surface of a neutron star that has the same mass as our sun and a
diameter of 21.0 km ? Take the mass of the sun to be ms = 1.99×1030
kg , the gravitational constant to be G...

A binary star system consists of two equal mass stars that
revolve in circular orbits about their center of mass. The period
of the motion, T = 26.4 days, and the orbital speed v = 220 km/s of
the stars can be measured from telescopic observations. What is the
mass (kg) of each star?
Best answer goes to the correct answer with steps thank you

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...

Suppose that a binary star system consists of two stars of equal
mass. They are observed to be separated by 360 million kilometers
and take 5.0 Earth years to orbit about a point midway between
them. What is the mass of EACH?

Suppose that a binary star system consists of two stars of equal
mass. They are observed to be separated by 325 million kilometers
and take 4.00 Earth years to orbit about a point midway between
them. What is the mass of each?

Two identical stars with mass M orbit around their center of
mass. Each orbit is circular and has radius R, so that the two
stars are always on opposite sides of the circle.
A) Find the orbital speed of each star and the period of the
orbit.
B) Suppose each identical mass for the binary stars is halved,
then the orbital period would change by:
a. Remain the same
b. Change by a factor of 1/?2
c. Change by a...

Neutron stars, such as the one at the center of the
Crab Nebula, have about the same mass as our sun, but a much
smaller diameter.
If you weigh 650 N on the earth, what would you weigh on the
surface of a neutron star that the same mass as our sun and a
diameter of 20.0 km?
