dc.description.abstractEnAbstract (2,250 Maximum Characters): In a previous work (Kaib et al. 2013), we showed that on Gyr timescales, stellar orbits of very wide binaries are often driven to very high eccentricities. In many instances, the resulting periastron passages are close enough for the two stars to destabilize one another's planetary system. In much rarer occurrences, the binary orbit becomes so eccentric that the two stars actually collide. We use numerical simulations to estimate the rate of stellar collisions within very wide binaries and then compare this rate to other known sources of stellar collisions within the Milky Way. Furthermore, we attempt to use Li abundances and stellar rotation rates to potentially identify such collision remnants among the Milky Way's thin disk population. Finally, we also investigate whether tidal dissipation during extremely close stellar encounters within very wide binaries can give rise to populations of other more exotic binary stars.
