| Abstract: | Stars in our galaxy, and likely the whole Universe, rarely reside alone. They are orbited by planets, other stars, and sometimes both. In this talk I will begin with a census of the varieties and importance of stellar companionship in astronomy. These pairs impact nearly everything we study, from cosmology to planetary habitability. I will then illustrate how recent large surveys have helped us improve theoretical models of star and planet formation. I will also emphasize the unique lessons we can learn from the companions that occupy the "in between:" not quite stars, and not quite planets. | |
