A certain binary system consists of two stars that have equal masses and revolve in circular orbits around a fixed point half-way between them. If the orbital velocity of each star is v=186 km/s and the orbital period of each is 11.3 days, calculate the mass M of each star. Give your answer in units of the solar mass, 1.99×1030 kg (e.g. if each planet's mass is 3.98×1030 kg, you would answer "2.00").
Consider a star orbited by two planets. Assume the star to have mass twice that of the Sun. Let planet 1 orbit with semi-major axis 10 AU, and eccentricity 0.6. Planet 2 orbits with semi-major axis 4 AU, and eccentricity 0. Assume the angular momentum vectors of the two planets to point in the same direction. Both planets have a mass of 1 Earth-mass. Let's assume these planets have a collision. a. At which point in its orbit must planet 1 be, at the time of collision? b. Assume the two planets stick together in the collision forming a planet with a mass of two earth-masses. What is the angular momentum and orbital energy (kinetic + potential) of the resulting planet? c. What are the semi-major axis and eccentricity of the orbit of the resulting planet?
