Astronomers have observed a small, massive object at the center of our Milky Way galaxy. A ring of material orbits this massive object; the ring has a diameter of about 10 light years and an orbital speed of about 210 km/s . A) Determine the mass of the massive object at the center of the Milky Way galaxy. Give your answer in kilograms. B) Give your answer in solar masses (one solar mass is the mass of the sun). C)...

Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0 x 1011 solar masses. A star orbiting near the galaxy's periphery is 5.7 x 104 light-years from its center. (a) What should the orbital period (in y) of that star be? 24.2e6 ху (b) If its period is 5.1 x 107 years instead, what is the mass (in solar masses) of the galaxy? Such calculations are used to imply the existence of other matter,...

Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0x10^11 solar masses. A star orbiting near the galaxy's periphery is 6.0X10^4 light years from its center. (For your calculations, assume that the galaxy's mass is concentrated near its center.) (a) What should the orbital period of that star be in yr ? (b) If its period is 6.0 x 10^7 years instead, what is the mass of the galaxy? Such calculations are used to...

It is said that at the center of every galaxy is a supermassive black hole (the picture below shows a picture towards the center of the Milky Way from the Keck Observatory). By observing the orbits of nearby stars, you can get a crude estimate of the mass of this black hole by assuming the stars have a circular orbit. Consider the star SO-2, which has an orbital period of 16.3 years. Its average distance from the black hole is...

Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This statement implies that the masses of the two stars are equal (see figure below). Assume the orbital speed of each star is |v vector| = 170 km/s and the orbital period of each is 14.5 days. Find the mass M of each star. (For comparison, the mass of our Sun is 1.99 times 10^30 kg.) 1.02e-9 If you...

Plaskett's binary system consists of two stars that revolve In a circular orbit about a center of mass midway between them. This statement implies that the masses of the two stars are equal (see figure below). Assume the orbital speed of each star is |v | = 240 km/s and the orbital period of each is 12.5 days.

Problem 4 In 1933 Fritz Zwiky used the virial theorem to demonstrate the existence of dark matter (even though nobody believed him for the subsequent 40 years) in the Coma cluster of galaxies. The demonstration assumes that the Coma galaxies have a random spherical distribution around the center of gravity of the cluster, and that their velocity is also distributed randomly. With these hypothesis the average potential energy of the cluster can be approximated with the potential energy of a...

Answer the questions below by assuming the spherical mass distribution of dark matter in our Galaxy, where the Galactic radius is 100,000 light years, the distance of the solar system from the center is 27,000 light years, and the constant orbital speed of stars is 220 km s1. Use the gravitational constant 6.674 x 10-11 N m2 kg2, light year 9.46 x 1015 m, and solar mass 2.0 x 1030 kg. 1. show the mass of dark matter inside radius...
