Abstract: In the subset of massive OB stars with strong global magnetic fields, X-rays arise from magnetically confined wind shocks resulting from the trapping and channeling of the stellar wind along magnetic field lines. However, it is not yet clear what the effect of stellar rotation and mass-loss rate is on these wind shocks and resulting X-rays. Here, we present results from a grid of Arbitrary Rigid-Field Hydrodynamic (ARFHD) simulations of a B-star centrifugal magnetosphere with an eye towards quantifying the effect of stellar rotation and mass-loss rate on the level of X-ray emission. The results are also compared to a generalized XADM model for X-rays in dynamical magnetospheres.
