Forming Mercury by a grazing giant collision involving similar mass bodies
Patrick Franco, Fernando Roig, Othon C. Winter +3
The origin of Mercury still remains poorly understood compared to the other rocky planets of the Solar System. One of the most relevant constraints that any formation model has to…

New versus past silica crush curve experiments: application to Dimorphos benchmarking impact simulations
Uri Malamud, Christoph M. Schafer, Irina Luciana San Sebastian +7
Crush curves are of fundamental importance to numerical modeling of small and porous astrophysical bodies. The empirical literature often measures them for silica grains, and diffe…

Metal-silicate mixing in planetesimal collisions
Kang Shuai, Christoph M. Schäfer, Christoph Burger +1
Impacts between differentiated planetesimals are ubiquitous in protoplanetary discs and may mix materials from the core, mantle, and crust of planetesimals, thus forming stony-iron…
