Abstract: |
Due to computational requirements and numerical difficulties associated with
coordinate singularity in spherical geometry, fully dynamic 3-D magnetohydrodynamic (MHD)
simulations of massive star winds are not readily available.
Here we report preliminary results of the first such a 3-D
simulation using θ1 Ori C (O5.5 V) as a model.
The oblique magnetic rotator θ1 Ori C is a source
of hard X-ray emitting plasma in its circumstellar environment.
Our numerical model can explain both
the hardness and the location of the X-ray emission from this star
confirming that a magnetically confined wind shock (MCWS) is the
dominating mechanism for hard X-rays in some massive stars. |
