ζ Phe is a 1.67-day spectroscopic binary with nearly circular orbits. The maximum measured Doppler shifts of the brighter and fainter components of the system are 121.4 km s−1 and 247 km s−1, respectively.
((a)) Determine the quantity msin3i for each star.
((b)) Using a statistically chosen value for sin3i that takes into consideration the Doppler-shift selection effect, estimate the individual masses of the components of ζ Phe.
