Using the center-of-mass equations or the Center of Mass Calculator (under Binary-Star Basics, above), you will investigate a specific binary-star system. Assume that Star 1 has  m1 = 3.2  solar masses, Star 2 has  m2 = 1.6  solar masses, and the total separation of the two (R) is 80 AU. (One AU is Earth's average distance from the Sun.) (a) What is the distance,  d1,  (in AU) from Star 1 to the center of mass?
Using the center-of-mass equations or the Center of Mass Calculator (under Binary-Star Basics, above), you will investigate a specific binary-star system.
