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 14 light-years and an orbital speed of about 100 km/s.
A. Determine the mass M 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. Many astronomers believe that the massive object at the center of the Milky Way Galaxy is a black hole. If so, what must the Schwarzschild radius RS of this black hole be?

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...

(25 points) A star known as S2 is in orbit around a massive, dark object thought to be a black hole at the center of the Milky Way Galaxy. Based on the spectral type of the star, S2's mass is about 15Mo. The period of the orbit is about 15 years, the eccentricity of the orbit is about 0.9, and the semimajor axis of the orbit is about 1000 AU. Remember that IAU = 1.5 × 1013 cm. In solar...
