Effects of Magnetic Pressure Support on Slim Accretion Disks

We explored the dynamics and structure of slim accretion disks. Specifically, we studied the effect of magnetic fields on the radial and vertical structure of the flow. We incorporated magnetic pressure via a polytropic formulation as well as by measuring directly from recent three-dimensional shearing box simulations. Qualitatively, we found that both prescriptions led to increased disk vertical scale height, although we expect detailed quantitative differences to have an observable impact on emergent spectra.
