Colliding high-speed winds light up cluster CHANDRA PHOTO RELEASE Posted: August 7, 2004
Named for its five brightest stars at infrared wavelengths, the Quintuplet is known to be home to hundreds of stars. Several of these are very massive stars that are rapidly losing gas from their surfaces in high-speed stellar winds. The bright point-like concentrations of 50 million degree Celsius gas in Chandra's image are thought to be caused by collisions between the high-speed winds in massive stars that have closely orbiting partners. Colliding stellar winds could also explain the diffuse X-radiation seen between the stars in the Quintuplet. The detection of radio waves from hot gas in this region provides further evidence for vigorous heating of gas by winds from massive stars. |
