XMM-Newton high-resolution X-ray spectroscopy of the Wolf-Rayet object WR25 (WN6ha+O4f)

[en] We report the analysis of the X-ray spectrum of the Wolf-Rayet star WR 25, observed by RGS and EPIC-MOS on board XMM-Newton. Temperatures up to 40 MK have been determined. Strong absorption, exceeding the value due to the Inter Stellar Medium (ISM) has been detected and assigned to the dense stellar wind. (C) 2003 COSPAR. Published by Elsevier Ltd.
