(Kutner 5.20) An astrometric binary is 10 pc from the Sun. The visible star orbits 2 arcsec from the center of mass with a period of 30 years. What is the mass of the unseen companion?
(based on Kutner problem 5.20) An astrometric binary is 10 pc from the Sun. The visible star orbits 2 arcsec from the center of mass with a period of 30 years. Based on this information, what constraint can you place on the total mass of the system? (Hint: you don't have enough information to find both masses, but you can find a lower limit to the total system mass.)
