We present a description of the data reduction methods and the derived catalog of more than 1600 X-ray point sources from the exceptionally deep 2003 January Chandra X-Ray Observatory (Chandra) observation of the Orion Nebula Cluster and embedded populations around OMC-1. The observation was obtained with Chandra's Advanced CCD Imaging Spectrometer (ACIS) and has been nicknamed the Chandra Orion Ultradeep Project (COUP). With an 838 ks exposure made over a continuous period of 13.2 days, the… 
We present a catalog of ∼14,000 X-ray sources observed by the ACIS instrument on the Chandra X-ray Observatory within a 1.42 deg2 survey of the Great Nebula in Carina, known as the Chandra Carina
High-Resolution Chandra X-Ray Imaging and Spectroscopy of the σ Orionis Cluster
We present results of a 90 ks Chandra X-ray observation of the young σ Orionis cluster (age ∼ 3 Myr ) obtained with the HETGS. We use the high-resolution grating spectrum and moderate-resolution CCD
Chandra observation of Cepheus A: The diffuse emission of HH 168 resolved
X-ray emission from massive stellar outflows has been detected in several cases. We present a Chandra observation of HH 168 and show that the soft X-ray emission from a plasma of 0.55 keV within HH
The Chandra X-ray view of the power sources in Cepheus A
The central part of the massive star-forming region Cepheus A contains several radio sources which indicates multiple outflow phenomena, yet the driving sources of the individual outflows have not
The Great Nebula in Carina provides an exceptional view into the violent massive star formation and feedback that typifies giant H ii regions and starburst galaxies. We have mapped the Carina
The first decade of science with Chandra and XMM-Newton
Some of the many discoveries made by Chandra and XMM-Newton that have transformed twenty-first century astronomy are highlighted.
X-ray flares in Orion low-mass stars
Context. X-ray flares are common phenomena in pre-main sequence stars. Their analysis gives insights into the physics at work in young stellar coronae. The Orion Nebula Cluster offers a unique
We present results of a sensitive Chandra X-ray observation and Spitzer mid-infrared (mid-IR) observations of the IR cluster lying north of the NGC 2071 reflection nebula in the Orion B molecular
The Chandra HETG Orion Legacy Project (HOLP) is the first comprehensive set of observations of a very young massive stellar cluster that provides high-resolution X-ray spectra of very young stars
X-rays from HH210 in the Orion nebula
We report the detection during the Chandra Orion Ultradeep Project (COUP) of two soft, constant, and faint X-ray sources associated with the Herbig-Haro object HH210. HH210 is located at the tip of


Chandra Observations of Variable Embedded X-Ray Sources in Orion. I. Resolving the Orion Trapezium
We used the High-Energy Transmission Grating Spectrometer on board the Chandra X-Ray Observatory to perform two observations, separated by 3 weeks, of the Orion Trapezium region. The zeroth-order
Chandra Observation of the ρ Ophiuchi Cloud
We observed a 17′ × 17′ region of the ρ Oph molecular cloud, using the ACIS-I array on board the Chandra X-Ray Observatory. A 100 ks exposure observation revealed ~100 X-ray sources above the
Chandra X-Ray Observation of the Orion Nebula Cluster. I. Detection, Identification, and Determination of X-Ray Luminosities
In this first of two companion papers on the Orion Nebula Cluster (ONC), we present our analysis of a 63 ks Chandra HRC-I observation that yielded 742 X-ray detections within the 30′ × 30′ field of
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 hr exposure in two observations. We detect
Deep ROSAT HRI Observations of the Orion Nebula
We present results from three deep ROSAT high-resolution imager observations of the Orion Nebula star-forming region. The X-ray images contain over 1500 cataloged stars in a roughly 0.8 sq deg region
Chandra X-Ray Observatory Study of the Orion Nebula Cluster and BN/KL Region
About 1000 X-ray emitting young pre–main-sequence (PMS) stars distributed in mass from ∼0.05 M☉ brown dwarfs to a ∼50 M☉ O star are detected in an image of the Orion Nebula obtained with the Advanced
An Overview of the Performance and Scientific Results from the Chandra X‐Ray Observatory
The Chandra X‐Ray Observatory (CXO), the X‐ray component of NASA’s Great Observatories, was launched on 1999 July 23 by the space shuttle Columbia. After satellite systems activation, the first
Advanced CCD imaging spectrometer (ACIS) instrument on the Chandra X-ray Observatory
The ACIS instrument has been operating for three years in orbit, producing high quality scientific data on a wide variety of X-ray emitting astronomical objects. Except for a brief period at the very
New weak-line T Tauri stars in Orion from the ROSAT all-sky survey
We present results of the spectroscopic and photometric follow-up observations of the ROSAT all- sky survey in the direction of the Orion cloud complex. The main goal of these observations is the
X-Ray Modeling of Very Young Early-Type Stars in the Orion Trapezium: Signatures of Magnetically Confined Plasmas and Evolutionary Implications
The Orion Trapezium is one of the youngest and closest star-forming regions within our Galaxy. With a dynamic age of ~3 × 105 yr, it harbors a number of very young hot stars, which likely are on the
