-The diagram shows the radial velocity curve of a double-line spectroscopic binary.Based on this radial velocity curve,what is the mass of star B compared to star A?

Question

Quizplus · Accepted Answer

In a double-line spectroscopic binary, the radial velocity curve shows the motion of both stars. If star B has a larger amplitude in its radial velocity curve compared to star A, it indicates that star B is less massive. Conversely, if star B has a smaller amplitude, it is more massive. The amplitude ratio is inversely proportional to the mass ratio, so if star B's amplitude is half that of star A, star B is twice as massive as star A.
