Evolutionary Memory in Binary Systems?
arXiv:astro-ph/0412185
Abstract
Correlation between the spins (rotational velocities) in binaries has previously been established. We now continue and show that the degree of spin correlation is independent of the components' separation. Such a result might be related for example to Zhang's non-linear model for the formation of binary stars from a nebula.
