What is the structure of NGC 1624-2.s giant magnetospherequestionMark

We propose to obtain new observations of the magnetic O star NGC 16242, whichhas the strongest magnetic field ever detected in a Ostar. With such a strongfield, NGC 16242 is trapping 95% of its wind into closed loops, and is a uniquelaboratory for the study of magnetically confined stellar winds. Two Chandraobservations, obtained at rotational phases when the magnetic field is theclosest to poleon and equatoron, respectively, revealed that the intrinsicXray emission produced within the magnetosphere is strong, but heavilyattenuated by the trapped wind. With the higher effective area of XMMNewton, wewill now use the variability of the Xray flux and hardness over the stellarrotation to diagnose the hot plasma structure of NGC 16242.s enormous magnetosphere. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
