A survey for Fe 6.4 keV emission in young stellar objects in rho Oph: the strong fluorescence from Elias 29
F. Favata, G. Micela, B. Silva +2
We report the results of a search for 6.4 keV Fe fluorescent emission in Young Stellar Objects (YSOs) with measured accretion luminosities in the rho Oph cloud, using all existing…
High Resolution X-ray Spectroscopy of Pre-Main-Sequence Stars: TWA 5 and PZ Tel
C. Argiroffi, J. J. Drake, F. R. Harnden +5
We report on the analysis of high resolution X-ray spectra of two pre-main-sequence stars: TWA 5 (observed with XMM-Newton) and PZ Telescopii (observed with Chandra/HETGS). TWA 5 i…
Chandra Orion Ultradeep Project: Observations and Source Lists
K. V. Getman, E. Flaccomio, P. S. Broos +21
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 January 2003 Chandra X-ray Observat…
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…
XMM-Newton observation of the young open cluster Blanco 1. I. X-ray spectroscopy and photometry
I. Pillitteri, G. Micela, S. Sciortino +2
We present an X-ray study of the high metallicity young open cluster Blanco 1 based on XMM--Newton data. X-ray spectroscopy of cluster members is presented for the first time as we…
High-amplitude, long-term X-ray variability in the solar-type star HD 81809: the beginning of an X-ray activity cycle?
F. Favata, G. Micela, S. L. Baliunas
We present the initial results from our XMM program aimed at searching for X-ray activity cycles in solar-type stars. HD 81809 is a G2-type star (somewhat more evolved than the Sun…
