WebThe lightest main sequence stars have a mass of 75 Jupiters. This will put the barycenter well outside the radius of either body for binary systems. A quick check of the two body system using the equation: R = 1 m 1 + m 2 ( m 1 r 1 + m 2 r 2) Setting m 1 = 75, r 1 = 1, m 2 = 13, r 2 = 2 gives: 75 + 26 75 + 13 = 1.147 http://spiff.rit.edu/classes/resceu/lectures/transit_ii/transit_ii.html
