Abstract:
In this work we profile the radiation deposition, and the velocity change, for a hazardous near-earth asteroid using a stand-off radiation source delivered at various heights-of-burst. For the radiation deposition, we compare results from analytic calculations, a particle transport code, and an adaptive-mesh radiation-hydrodynamic code; the change in velocity is computed using an adaptive-mesh radiation-hydrodynamic code. The nominal heights-of-burst will be compared, and applied to the potential deflection of the asteroid 101955 Bennu.
