DESCRIPTION:Speaker: Katie Breivik\nhosted by Ilaria Caiazzo\nAbstract: Abs
 tractBinary stars play a role in nearly all areas of astrophysics from pro
 viding high-energy radiation that drove reionization of neutral hydrogen i
 n the early Universe to forming compact objects to being contamination sou
 rces for exoplanet population studies. While theoretical descriptions for 
 the outcomes of binary star interactions quickly followed the confirmation
  that nuclear fusion powers stellar evolution\, models which accurately de
 scribe all aspects of binary evolution\, from birth through to the formati
 on of stellar remnants\, remain elusive. This is due\, at least in part\, 
 to a relative dearth of data sets that provide measurements of binary prop
 erties and cover swaths of stellar population parameters like mass and tem
 perature. The development of several astronomical surveys which span both 
 the electromagnetic and gravitational wave spectra\, and provide measureme
 nts of binary-star parameters\, offer a unique opportunity to confront mod
 els for binary evolution with data. In this colloquium I will review how u
 ncertain binary interactions shape stellar populations and discuss recent 
 work which aims to constrain these interactions by comparing binary evolut
 ion simulations to data using a variety of analysis techniques that target
  both large populations as well as individual systems of interest.
