Predicting asteroid material properties from a DART-like kinetic impact
Kathryn M. Kumamoto, J. Michael Owen, Megan Bruck Syal +7
NASA's Double Asteroid Redirection Test (DART) mission is the first full-scale test of the kinetic impactor method for asteroid deflection, in which a spacecraft intentionally impa…
Influence of the projectile geometry on the momentum transfer from a kinetic impactor and implications for the DART mission
S. D. Raducan, M. Jutzi, T. M. Davison +5
The DART spacecraft will impact Didymos's secondary, Dimorphos, at the end of 2022 and cause a change in the orbital period of the secondary. For simplicity, most previous numerica…
CRKSPH-compatible discretization of the SUPG and SAAF transport equations
Brody R. Bassett, J. Michael Owen
The self-adjoint angular flux and streamline-upwind Petrov-Galerkin transport equations are discretized using reproducing kernels with the collocation method to produce a discretiz…
Meshless discretization of the discrete-ordinates transport equation with integration based on Voronoi cells
Brody R. Bassett, J. Michael Owen
The time-dependent radiation transport equation is discretized using the meshless-local Petrov-Galerkin method with reproducing kernels. The integration is performed using a Vorono…
Efficient smoothed particle radiation hydrodynamics II: Radiation hydrodynamics
Brody R. Bassett, J. Michael Owen, Thomas A. Brunner
The radiation hydrodynamics equations for smoothed particle hydrodynamics are derived by operator splitting the radiation and hydrodynamics terms, including necessary terms for mat…
Efficient smoothed particle radiation hydrodynamics I: Thermal radiative transfer
Brody R. Bassett, J. Michael Owen, Thomas A. Brunner
This work presents efficient solution techniques for radiative transfer in the smoothed particle hydrodynamics discretization. Two choices that impact efficiency are how the materi…
