The Formation and Evolution of Multiple Stellar Systems
Kaitlin Kratter



Binary and multiple stellar systems are common outcomes of the star formation process. More importantly, they account for a disproportionately large fraction of our knowledge on a wide array of topics from stellar structure to cosmology. In this talk I will discuss the intersection of binary formation and planet formation. I will describe several formation mechanisms for multiple star systems, focusing on the role of protostellar accretion disks and on the boundary between binaries and planets. Next I will examine the evolution of higher order multiples, showing how the interplay between dynamics and stellar evolution can produce odd-ball evolved binaries, and frequent stellar collisions.
