SUMMARY:White Dwarf Binaries across the H-R diagram\, Astronomy Colloq
 uium\, Dr. Borja Anguiano\, University of Notre Dame
DESCRIPTION:The evolution of multiple-star systems is a fundamental qu
 estion in stellar astrophysics where around 25% of the binary systems 
 are compact enough to exchange mass\, changing the structures and subs
 equent evolution of both stars. Muti-object-wavelength-epoch massive s
 tellar spectroscopic surveys are opening a new era to study the proper
 ties of compact binaries across the H-R diagram. In this talk I discus
 s the recent APOGEE-GALEX-Gaia Catalog (AGGC) of candidate compact bin
 aries containing potential WD stars. Numbering over 3400 sources\, the
  size of this catalog is comparable to that of previous WDMS catalogs 
 but includes secondary companions in the MS\, subgiant branch\, RGB\, 
 and red clump (RC) phases of evolution\, as well as systems that occup
 y the MS binary and sub-subgiant (SSG) regions of the H-R diagram.
