X-ray emitting young stars in the Orion Nebula
The Orion Nebula Cluster and the molecular cloud in its vicinity have been observed with the ACIS-I detector on board the Chandra X-ray Observatory with 23 hours exposure in two observations. We detect 1075 X-ray sources, most with sub-arcsecond positional accuracy. Ninety-one percent of the sources are spatially associated with known stellar members of the cluster, and an additional 7% are new...
متن کاملX-ray Emission from Orion Nebula Cluster Stars with Circumstellar Disks and Jets
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 circumstellar disks (“proplyds”) and optical jets in Hubble Space Telescope (HST) imaging. Our study uses X-ray data acquired during Chandra Orion Ultradeep Program (COUP) observations, as well as complementary optical ...
متن کاملThe distance to the Orion Nebula
We have used the Very Long Baseline Array to measure the trigonometric parallax of several member stars of the Orion Nebula Cluster showing non-thermal radio emission. We have determined the distance to the cluster to be 414 ± 7 pc. Our distance determination allows for an improved calibration of luminosities and ages of young stars. We have also measured the proper motions of four cluster star...
متن کاملThe Orion Nebula in the mid - Ir
We present two wide-field (≈ 5 × 3.5), diffraction limited (λ/D ≃ 0.5 at 10 μm), broad-band 10 μm and 20 μm images of the Orion Nebula, plus six 7–13 μm narrow-band (λ/∆λ ≃ 1) images of the BN/KL complex taken at the 3.8m UKIRT telescope with the MPIA MAX camera. The wide field images, centered on the Trapezium and BN/KL regions, are mosaics of 35 × 35 frames obtained with standard chopping and...
متن کاملThe Orion Nebula in the Mid-infrared
Q1 We present two wide-field ( 50 ; 3A5), diffraction-limited (k=D ’ 0B5 at 10 m), broadband 10 and 20 m images of the Orion Nebula, plus six 7–13 m narrowband (k= k ’ 1) images of the BN/KL complex taken at the 3.8 m UKIRT Q2 telescope with the MPIA MAX camera. The wide-field images, centered on the Trapezium and BN/KL regions, are mosaics of 3500 ; 3500 frames obtained with standard chopping ...
