Hunting a black hole. Observations of the light from a certain star indicate that it is part of a binary (two-
star) system. This visible star has orbital speed v = 270 km/s, orbital period T = 23.1 days, and approximate
mass m₁ = 5.7M², where Ms is the Sun's mass, 1.99 x 10³0 kg. Assume that the visible star and its
companion star, which is dark and unseen, are both in circular orbits (see the figure). Find the ratio of the
approximate mass m2 of the dark star to Ms.

- A number of gas giant planets orbiting other stars at distances less than 1 A.U. have been discovered. Because of their proximity to their parent stars, and their compositional similarity to Jupiter, they have been labeled “Hot Jupiters”. The orbital radius of one of these planets is 0.06 A.U. with average orbital speed 600 km/sec. What is the length of this planet’s year in Earth (solar) days? Estimate the mass, M, of its parent star in terms of the mass of the sun (M) using Newton’s first form of Kepler’s 3rd Law. Calculate the star’s luminosity, L, in terms of the luminosity of the sun (L☉), Note: (LL=MM4where L ~ 4 × 1026 W ). The radius of this planet is 1.5 times the radius of Jupiter.
