The authors explore the evolution of wide binaries in the solar neighborhood driven by perturbations from passing stars and giant molecular clouds. They develop a Monte Carlo technique which exploits the fact that most perturbers encounter a wide binary at large impact parameter so that their cumulative effect may be described as a diffusion process. The rare catastrophic encounters are treated individually. It is shown that the effects of stars and clouds interact in disrupting a binary. Two possible evolutionary scenarios for the population of wide binaries are studied: (1) a "burst" model, in which a particular distribution of binaries in semimajor axis is created initially and evolved; and (2) a "continuous creation" model, in which a population is continuously created with a particular distribution in semimajor axes. The authors also address the period stability and lifetime of the proposed solar companion.
