The origins of binary stars and their planetary systems

Binary stars are common and exert an outsize impact on many areas of astrophysics. They are the source of a wide range of phenomena from type Ia supernovae to gravitational wave sources. In this talk I will emphasize the new statistical leverage on binary statistics and formation models provided by large surveys such as Gaia and SDSS IV. I will show how the variance of the observed binary occurrence rates as a function of stellar mass, period, and metallicity can inform our understanding of planetary statistics, and even help identify better targets for habitable planet searches.
