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. Find the mass M of each star. (For comparison, the mass of our Sun is 1.99 times 1030 kg Your answer...

Next stop is our nearest star: Alpha Centauri. Your Journey will take a while using fusion power, so you will probably sleep for a few months. When you finally wake up near Alpha Centauri, you realize that Alpha Centauri is actually a binary star system! The two stars, Alpha-Cen-A and AlphaCen-B, have different masses; Alpha-Cen-A is more massive than Alpha-Cen-B. (a) Draw a schematic diagram representing the orbits of the two stars, labeling the stars and indicating their orbital paths....

The spectral lines of two stars in a particular eclipsing binary system shift back and forth with a period of 6 months. The lines of both stars shift by equal amounts, and the amount of the Doppler shift indicates that each star has an orbital speed of 1.2×105 m/s relative to the other. What are the masses of the two stars? Assume that each of the two stars traces a circular orbit around their center of mass. (Hint: See Mathematical...

Plaskett's binary system consists of two stars that revolve in circular orbits around a fixed point half-way between them. This means that the masses of the two stars are equal (see the figure below). --- M If the orbital velocity of each star is v= 188 km/s and the orbital period of each is 11.7 days, calculate the mass Mof each star. (For comparison, the mass of our Sun is 1.99x1030 kg.)

The spectral lines of two stars in a particular eclipsing binary system shift back and forth with a period of 10 months. The lines of both stars shift by equal amounts, and the amount of the Doppler shift indicates that each star has an orbital speed of 105 m/s. What are the masses of the two stars? Assume that each of the two stars traces a circular orbit around their center of mass.
