Colloquium by Kaitlin Kratter, Arizona
We have known for decades that binary and multiple star systems are very common, with occurrence rates that are strong functions of mass. Nevertheless, models of single, isolated star formation persist in textbooks and the literature. In this talk I will provide an overview of the pathways to multiple star formation, emphasizing that the majority of stars, including low mass stars, begin their lives as binaries or multiples. I will discuss the improving agreement between theoretical models, numerical simulations, and observational surveys. Due to the very high frequency of stars formed as part of a multiple systems, planet formation should be strongly influenced by stellar companions. I will discuss the statistical evidence for its impact and ongoing work to include multiplicity in planet formation models.
