Spectra are taken of two stars in a binary system: Star A andStar B. Every 1.56 days, the H? line in star A goes from 2.5 ?Ablueward of its rest (laboratory) wavelength to 2.5 ?A redward thenback to 2.5 ?A blueward. The H? line in star B also cycles throughshifts redward then blueward and back to redward with respect tothe rest (laboratory) wavelength of H? every 3.96 days but itsmaximum deviation from the rest wavelength is 3.5 ?A. (a.) If theinclination of the system is unknown, estimate as best you can eachstar’s mass. Report your answer in units of solar masses. (b.)Given you measured a Doppler shift of the lines, would you expectthis system to be eclipsing? Why or why not? (c.) If you suspectedthe lower mass star in the system was a White Dwarf, can you putany limits on the inclination of the system?
