The spectral lines of two stars in a particular eclipsing binary system shift back and forth with a period of 3 months. The lines of both stars shift by equal amounts, and their Doppler shifts indicate an orbital speed of 88,000 m/s for Star 1 relative to Star 2. 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 Insight 15.4.)
