Radiation hydrodynamics under extreme conditions 2024 2024-07-11 Describing the dynamics of optically thick, accelerating media involves intricate interactions between gas and radiation. These effects are the main drivers in the outflows of various diverse classes of objects nearing or exceeding the Eddington limit. Prominent examples include Wolf-Rayet (WR) stars and Luminous Blue Variables (LBVs), distinguished by their continuous or eruptive optically thick winds. This presentation delves into the complexities of Radiation Hydrodynamics Under Extreme Conditions, aiming to address unresolved observational and theoretical challenges while attempting to offer some insights into potential solutions.
