ABSTRACT
We propose to improve our understanding of structures of stellar winds and their implications on the X-ray emission of massive stars by collecting a high-quality, high-resolution RGS spectrum of the O6Ief supergiant lambda Cep. This object shares many properties with the well-observed O4Ief supergiant zeta Pup which turned out to be an incredible puzzle: its X-ray spectrum meets very well the expectations of the wind-embedded shock model, although zeta Pup is not a `normal' O-type star. This situation contrasts with that of the other more normal, single O-type stars observed in high resolution so far. lambda Cep offers a unique opportunity to investigate the X-ray emission of the sole twin of zeta Pup, and hence to draw a much clearer picture of the high-energy emission of single massive stars.

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
