X-ray Properties of Young Stellar Objects in OMC-2 and OMC-3 from the Chandra X-ray Observatory

چکیده
We report X-ray results of the Chandra observation of Orion Molecular Cloud 2 and 3. A deep exposure of ∼ 100 ksec detects ∼ 400 X-ray sources in the field of view of the ACIS array, providing one of the largest X-ray catalogs in a star forming region. Coherent studies of the source detection, time variability, and energy spectra are performed. We classify the X-ray sources into class I, class II, and class III + MS based on the J, H, and K -band colors of their near infrared counterparts and discuss the X-ray properties (temperature, absorption, and time variability) along these evolutionary phases. Subject headings: stars: pre-main sequence — X-rays: stars — infrared: stars — Individual: OMC-2,

Discovery of X Rays from Class 0 Protostar Candidates in Omc-3
We have observed the Orion Molecular Clouds 2 and 3 (OMC-2 and OMC-3) with the Chandra X-ray Observatory (CXO). The northern part of OMC-3 is found to be particularly rich in new X-ray features; four hard X-ray sources are located in and along the filament of cloud cores. Two sources coincide positionally with the submm-mm dust condensations of MMS 2 and 3 or an outflow radio source VLA 1, whic...
متن کاملChandra Observations of Embedded Young Stellar Objects
This paper reviews the results of the Chandra deep exposure observations on star forming regions. The ρ Ophiuchi (ρ Oph) cloud cores B-F reveal ∼ 100 X-ray sources above the detection limit of ∼10 ergs s. About 2/3 of the X-ray sources are identified with an optical and/or infrared (IR) object, including significant numbers of class I sources. The class I sources exhibit higher temperature plas...
متن کاملForty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملA High-Resolution Very Large Array Observation of a Protostar in OMC-3: Shock-induced X-ray Emission by a Protostellar Jet
Using the Very Large Array (VLA) in the A-configuration, we have obtained a high-resolution 3.6 cm map of a hard X-ray source detected by the Chandra X-ray Observatory in a protostellar clump in Orion molecular cloud 3. Two radio continuum sources were detected in the vicinity of the X-ray source, both of which have NIR counterparts. We conclude that these VLA sources are free-free emission pro...
متن کاملDeep near Infrared Observations of the X-ray Emitting Class 0 Protostar Candidates in the Orion Molecular Cloud-3
We obtained near infrared (NIR) imaging with the Subaru Telescope of the class 0 protostar candidates in the Orion Molecular Cloud-3, two of which were discovered to have X-ray emission by the Chandra X-ray Observatory. We found strong evidence for the class 0 nature of the X-ray sources. First, our deep K -band image shows no emission brighter than 19.6 mag from both of these X-ray sources. Si...
