Eclipsing Binary Brown Dwarfs (Artist's Schematic View)

About this video
Duration: 8 seconds

This video presents a greatly simplified, schematic view of a pair of brown dwarfs orbiting each other. The binary dwarf system lies in the Orion nebula. The binary pair is too close to be resolved with present-day telescopes. This is an artistic oblique view of the system. In reality, the orbital plane is tilted edge-on to Earth such that the stars are seen eclipsing each other. Eclipses can be frequently observed because the dwarfs complete an orbit approximately once every ten days. Eclipsing binaries allow precise measurements of each companion star's mass, diameter, surface temperature, and intrinsic brightness.
