(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...

The orbit of a planet around its star is an ellipse with the star at one focus. The apoapsis of a planet is its greatest distance from the star and the periapsis is it shortest distance. Its mean distance is the length of thr semimajor acid. The apoapsis of a planet is 451 million miles. If the star is 34.4 million miles from the center of the orbit, what is the periapsis? What is the mean distance? Write an equation...

In a particular binary star system, only one star is visible because the other star is too faint to see at that distance. An astronomer measures the size (semimajor axis) and period of the orbit of the visible star. From this information the astronomer can calculate nothing about the mass—both stars have to be visible to do so. the mass of each star. the sum of the masses of the two stars but not the mass of each star separately....
