Stellar Activity on the Young Suns of Orion: COUP Observations of K5-7 Pre-Main Sequence Stars
نویسنده
چکیده
In January 2003, the Chandra Orion Ultradeep Project (COUP) detected about 1400 young stars during a 13.2 day observation of the Orion Nebula Cluster (ONC). This paper is a study of the X-ray properties of a well-defined sample of 28 solar-mass ONC stars based on COUP data. Our goals are to characterize Universe Division, Science Mission Directorate NASA Headquarters

X-rays, Pre-main Sequence Stars and Planet Formation
The study of magnetic activity of pre-main sequence (PMS) stars through their X-ray emission is entering a mature phase. We review here two recent developments. First, we present some early findings from the Chandra Orion Ultradeep Project (COUP) relating to the age-activity-rotation relations of PMS stars. COUP is a nearly continuous exposure of the Orion Nebula Cluster over 13 days and gives ...
متن کاملIron fluorescent line emission from young stellar objects in the Orion Nebula
We present the result of a systematic search for the iron Kα fluorescent line at ∼ 6.4 keV among 1616 X-ray sources detected by ultra-deep Chandra observations of the Orion Nebula Cluster and the obscured Orion Molecular Cloud 1 population as part of the Chandra Orion Ultra-deep Project (COUP). Seven sources are identified to have an excess emission at ∼ 6.4 keV among 127 control sample sources...
متن کاملBright X-ray Flares in Orion Young Stars from Coup: Evidence for Star-disk Magnetic Fields?
We have analyzed a number of intense X-ray flares observed in the Chandra Orion Ultradeep Project (COUP), a 13 days observation of the Orion Nebula Cluster (ONC), concentrating on the events with the highest statistics (in terms of photon flux and event duration). Analysis of the flare decay allows to determine the physical parameters of the flaring structure, in particular its size and (using ...
متن کاملTHE EFFECT OF COSMIONS ON THE STABILITY OF MAIN SEQUENCE STELLAR CORES
We have studied the effect of hypothetical Cosmions on the core stability of main sequence stars (of populations I and II). Cosmions, with a mass of 4-10 Gev/c2 and a scattering cross section with nucleons of approximately 10-36 cm2 could prevail in transporting heat in the stellar cores. Raby [17] showed the existence of a local thermal instability caused by the presence of Cosmions in the sol...
متن کاملThe Low Mass Stellar Population of the Orion Ob1 Association and Implications for the Formation of Low Mass Stars
The OB associations, which are fossil star formation regions, retain the endproducts of the star formation process in an open, unobscured environment. Observations of the low mass stars in OB associations provide a far clearer picture of the results of the star formation process than do observations of embedded, on-going star formation regions. We review the X–ray and optical surveys of the fos...
