WebTable 6.1. End products of stellar evolution as a function of stellar mass, for single stars and for components of close binary stars (roughly, those undergoing case B mass transfer). The columns ‘He-core mass’ give the maximum mass of the helium core reached by a star of the given initial mass range, for single and close binary stars. WebA binary star system, which is quite common, will allow us to determine mass with great accuracy, using Kepler's Third Law of Planetary Motion which is as follows: T 2 r 3 = 4 π 2 G M s u m.
