Discovery of X-ray eclipses from the transient source CXOGC J174540.0-290031 with XMM-Newton
D. Porquet, N. Grosso, G. Belanger +4
We present the XMM-Newton observations obtained during four revolutions in Spring and Summer 2004 of CXOGC J174540.0-290031, a moderately bright transient X-ray source, located at…
X-ray Emission from Orion Nebula Cluster Stars with Circumstellar Disks and Jets
Joel H. Kastner, Geoffrey Franz, Nicolas Grosso +5
We investigate the X-ray and near-infrared emission properties of a sample of pre-main sequence (PMS) stellar systems in the Orion Nebula Cluster (ONC) that display evidence for ci…
Global X-ray properties of the Orion Nebula region
Eric D. Feigelson, Konstantin Getman, Leisa Townsley +6
Based on the Chandra Orion Ultradeep Project (COUP) observation, we establish the global X-ray properties of the stellar population associated with the Orion Nebula. Three componen…
X-ray emission from young brown dwarfs in the Orion Nebula Cluster
Thomas Preibisch, Mark J. McCaughrean, Nicolas Grosso +8
We use the sensitive X-ray data from the Chandra Orion Ultradeep Project (COUP) to study the X-ray properties of 34 spectroscopically-identified brown dwarfs with near-infrared spe…
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…
Enhanced X-ray variability from V1647 Ori, the young star in outburst illuminating McNeil's Nebula
N. Grosso, J. H. Kastner, H. Ozawa +5
We report a ~38 ks X-ray observation of McNeil's Nebula obtained with XMM on 2004 April 4. V1647 Ori, the young star in outburst illuminating McNeil's Nebula, is detected with XMM…
