A new study has caught a newborn star similar to the sun in a fiery outburst. X-ray observations of the flare-up, which are the first of their kind, are providing important new information about the early evolution of the sun and the process of planet formation.
The study, which was conducted by a team of astronomers headed by Joel Kastner of the Rochester Institute of Technology that included David Weintraub from Vanderbilt, is reported in the July 22 issue of the journal Nature.
Last January, Jay McNeil, an amateur astronomer in west Kentucky, discovered a new cloud of dust and gas in the Orion region. Previously, the cloud, now named the McNeil nebula, was not visible from earth. But a new star inside the dark cloud had flared up in brightness, lighting up the surrounding nebula. Looking back at the images taken of this part of the sky revealed that a young star about the size of the sun had burst into visibility last November.
