Chandra resolves the double FU Orionis system RNO 1B/1C in X-rays.

SKINNER S.L. and GUDEL M.

Abstract (from CDS):

We present new Chandra X-ray observations of the close pair of young stars RNO 1B and 1C (6'' separation) located in the L1287 cloud. RNO 1B erupted in 1978-1990 and is classified as an FU Orionis star (FUor). RNO 1C also shows most of the properties of an FUor but no eruption has been seen yet. Only a few dozen FUors are known and the presence of two such objects with a small angular separation is rare, suggesting a common origin. Both stars were faintly detected by Chandra and we summarize their X-ray properties within the framework of other previously detected FUors. We also report other X-ray detections in L1287 including the deeply embedded young star RNO 1G, the jet-like radio source VLA 3, and an enigmatic hard flaring source with no Two Micron All Sky Survey counterpart that was only detected in the second of the two Chandra exposures.
