4U0114+65 outer wind

We propose to use the unique high resolution capabilities of XMMNewton to studyin depth the stellar wind structure and properties of the B supergiant donor inthe wind accreting pulsar 4U0114+65. The goal is to put further observationalconstrains on the current models of stellar winds in massive stars using thepoint like source of ionizing Xrays as a probe. In particular we want to studythe ionized wind of 4U0114+65 in the outer region r > 2R which, to date, remainslargely unexplored (most ionized winds are studied at r < 2R , where the windinstabilities are already well developed) and answer a funda mental question:is the wind clumped or smooth at r > 2R ? truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
