You should now see that the reason the mass of the star in Part A must be inferred is that the star has no known orbiting objects, which means we cannot apply Newton’s version of Kepler’s third law. Which of the following must be true if the star’s inferred mass is to be accurate?

A. We have determined that the star is a main-sequence star. B. We have measured the star’s velocity. C. The star must be located within the Milky Way Galaxy and not in another galaxy. D. We have measured the star’s spectral type.
