COUP census of X-ray stars in BN-KL and OMC-1S
N. Grosso, E. D. Feigelson, K. V. Getman +11
We present a study of the X-ray sources detected in the vicinity of two density peaks in the Orion Molecular Cloud 1 (OMC-1) behind the Orion Nebula Cluster (ONC), as seen in the e…
X-rays from star-forming regions: New objects, new physics, new visions
T. Montmerle, N. Grosso, E. D. Feigelson +1
Star-forming regions have been the targets of X-ray observations since the dawn of satellite X-ray astronomy. The increase in sensitivity and/or spatial resolution offered by XMM-N…
Imaging and spectroscopy of DENIS-P J104814-395606
Ralph Neuhaeuser, Eike Guenther, Joao Alves +8
We obtained deep H- and K-band images of DENIS-P J104814-395606 using SofI and the speckle camera SHARP-I at the ESO-3.5m-NTT as well as QUIRC at the Mauna Kea 2.2m telescope betwe…
X-rays and regions of star formation: a combined ROSAT-HRI/near-to-mid IR study of the rho Oph dark cloud
Nicolas Grosso, Thierry Montmerle, Sylvain Bontemps +2
We have obtained two deep exposures of the rho Oph cloud core region with the ROSAT HRI. The improved position accuracy (1"-6") with respect to previous recent X-ray observations (…
