Prof. Gizis discovers an "ultracool" brown dwarf that can generate flares stronger than the sun's

June 13, 2016 - Although astronomers often refer to brown dwarfs as “failed stars,” scientists at the University of Delaware have discovered that at least one of these dim celestial objects can emit powerful flashes of light. A research team led by Prof. Gizis, has discovered an “ultracool” brown dwarf known as 2MASS 0335+23, with a temperature of only 4400°F that can generate flares stronger than the sun’s. Gizis reported on the finding on June 13 at the annual meeting of the American Astronomical Society in San Diego.
