Prof. Burgasser and UC San Diego Ph.D. alum Chih-Chun “Dino” (now postdoc at Northwestern University) published a stunning paper on one of the most tiniest binary stars. The discovery was announed at the  241stAmerican Astronomical Society Meeting. The binary is a pair of ultracool dwarfs that orbit each other in just 20.5 hours. The star system is the lowest-mass binary ever found, and this discovery launches new questions about how common these tight cool binaries exist.
