[182.26] Computer modeling of X-ray emission and absorption in the context of hot star winds

C.B. Abing, N.A. Miller (University of Wisconsin-Eau Claire)

In support of ongoing studies of the X-ray emission from hot stars, we have been working on simulations of the X-ray output from mixtures of plasmas at wide ranges of temperature. These simulations have been carried out using the Spect3D, Spect3D Visualizer, and Plasma Grid Generator programs developed by Prism Computational Sciences. The Spect3D code allows construction of a plasma of arbitrary geometry and composition, and can then be used to calculate the observed spectrum for any direction of observation. Our initial studies have concentrated on simple geometric situations to build the foundations for more complicated spherical geometries. While the initial simulations used a mixture of hydrogen, helium, and oxygen, later simulations are including all important elements in their astrophysical abundances. We acknowledge support from Research Corporation, NASA grant GO4-5015B, and the University of Wisconsin-Eau Claire.
