Numerical Experiments on the DECA1" of ThreeBody Systems
Abstract
Numerical results are presented for calculations of stellar threebody systems. Among the triple systems with similar initial separations between each of the stars, the equalmass systems are most stable with typical halflives of about 40 crossing times. In the other extreme, systems with a very small total angular or a large mass difference have halflives of only about 10 crossing times. The escaping star is usually the lightest one, while the escape probability for the heaviest star approaches zero when its mass exceeds the combined smass of the other two stars by more than a factor of about 5. The final binary becomes very eccentric (e 0.8) when the three stars are restricted to a plane and do not have a very high total angular momentum, or when the total angular momentum is very small.
