Orbits of Binary Ultracool Dwarfs

This animation illustrates research by UT Austin astronomer Trent Dupuy and University of Hawaii astronomer Michael Liu. You can read the news release detailing the research here:

The animation shows all 20 binaries used in the Dupuy & Liu study of brown dwarf masses. Each system is orbiting around its center of mass, which is marked by an 'x.' Colors indicate surface temperatures, from warmest to coolest: gold, red, magenta, or blue. The orbit sizes shown in the animation are accurate relative to each other. The animation is also in extreme fast-forward, where every one second in the animation corresponds to approximately two years of real time.
