A group of astronomers using the Hubble Space Telescope and Chandra X-ray Observatory, in concert with other telescopes, have directly detected for the first time a new type of stellar flare occurring in a narrow temperature range of gas on a star other than the sun. Rachel Osten, a graduate student at the University of Colorado at Boulder, said the flares were detected on a star, known as binary system HR 1099, in a very narrow temperature range of gas recorded in the ultraviolet portion of the light spectrum, but not in the higher energy X-ray region.
