Iron Fluorescent Line Emission from Young Stellar Objects in the Orion Nebula
M. Tsujimoto, E. D. Feigelson, N. Grosso +5
We present the result of a systematic search for the iron Kalpha fluorescent line at 6.4 keV among 1616 X-ray sources detected by ultra-deep Chandra observations of the Orion Nebul…
An X-ray census of young stars in the Chamaeleon I North cloud
Eric D. Feigelson, Warrick A. Lawson
Sensitive X-ray imaging surveys provide a new and effective tool to establish the census of pre-main sequence (PMS) stars in nearby young stellar clusters. We report here a deep Ch…
The Chandra Deep Field-North Survey: XVII. Evolution of magnetic activity in old late-type stars
E. D. Feigelson, A. E. Hornschemeier, G. Micela +11
The extremely sensitive Chandra Deep Field-North (CDF-N) pencil-beam X-ray survey is used to identify and characterize the X-ray emission from old high-latitude main sequence Galac…
The Spectra and Variability of X-ray Sources in a Deep Chandra Observation of the Galactic Center
M. P. Muno, J. S. Arabadjis, F. K. Baganoff +7
We examine the X-ray spectra and variability of the sample of X-ray sources with L_X = 10^{31}-10^{33} erg s^{-1} identified within the inner 9' of the Galaxy. Very few of the sour…
Chandra observation of an unusually long and intense X-ray flare from a young solar-like star in M78
N. Grosso, T. Montmerle, E. D. Feigelson +1
LkHA312 has been observed serendipitously with the ACIS-I detector on board Chandra with 26h continuous exposure. This H_alpha emission line star belongs to the star-forming region…
Diffuse X-ray Emission in a Deep Chandra Image of the Galactic Center
M. P. Muno, F. K. Baganoff, M. W. Bautz +6
We examine the spectrum of diffuse emission detected in the 17' by 17' field around Sgr A* during 625 ks of Chandra observations. The spectrum exhibits He-like and H-like lines fro…
