A binary star system, in which the star (a) has a radius of Ra = 1.7 Ro, an effective temperature of Ta = 9900k , and a mass of the star(a) Ma = 2.0 Mo . The star (a) was observed with a wavelength ( 6000 A°) and the amount of change At wavelength (0.8 A°), the star (b) has a radius of Rb = 0.9Ro, a temperature of Tb = 5300 K, and a mass of the star (b) Mb = 0.9Mo. These two stars orbit in circular orbits around their common center of mass, with a period P = 40 days What is the orbital speed of each star with respect to the center of mass?
