ABSTRACT
We propose to obtain the first high-resolution spectrum of a single Wolf-Rayet (WR) type star. WR stars are immediate progenitors of core-collapse SNe and GRBs. The low-resolution spectra accumulated by XMM-Newton and Chandra revealed that the X-ray emission of WR stars depends on yet unknown factors - wind anisotropy, magnetic field and rotation are possible suspects. The RGS spectrum of the X-ray brightest single WR star, WR 6, analyzed by means of comprehensive models, will unveil how X-rays are produced in WR stars. The wind shock origin of X-rays will be firmly proved or disproved. The unique capabilities of XMM-Newton will elevate our knowledge about massive stars in their latest evolutionary stages to a qualitatively new level.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
