COUP census of X-ray stars in BN-KL and OMC-1S
N. Grosso, E. D. Feigelson, K. V. Getman +11
We present a study of the X-ray sources detected in the vicinity of two density peaks in the Orion Molecular Cloud 1 (OMC-1) behind the Orion Nebula Cluster (ONC), as seen in the e…
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…
Discovery of X-ray emission from the proto-stellar jet L1551 IRS5 (HH 154)
Fabio Favata, C. V. M. Fridlund, G. Micela +2
We have for the first time detected X-ray emission associated with a proto-stellar jet, on the jet emanating from L1551 IRS5. The IRS5 proto-star is hidden beyond a very large abso…
A BeppoSAX and ROSAT view of the RCW86 supernova remnant
F. Bocchino, J. Vink, F. Favata +2
We present a spectral analysis of the Northern and Southwestern rim of the RCW86 X-ray shell, pointing out the remarkable differences between these two parts of the same object. In…
An extreme X-ray flare observed on EV Lac by ASCA in July 1998
F. Favata, F. Reale, G. Micela +3
We present a long (150 ks elapsed time) ASCA X-ray observation of the dM3.5e star EV Lac, during which an exceptionally intense flaring event (lasting approximately 12 ks) was obse…
