“The Formation and Evolution of Binary Stars"

by

Aaron T. Lee, PhD, St. Mary's College

With nearly 50% of the stars we see in the sky being part of binary systems, binarity and multiplicity of stars is a common phenomenon in the Milky Way Galaxy. With this percentage measured even higher in star-forming regions, the formation of binaries appears to be part of the star-formation process. This talk will discuss the formation of stars and how this process helps us to better understand the prevalence of binary star systems in the Milky Way Galaxy and how modern-day observations of stars and galaxies rely on our understanding of stellar binarity.
