Thermal Conductivity Measurements of Planetesimal Dust Analogs

Institut fur Geowissenschaften, Universitat Heidelberg, Germany. In the context of laboratory experiments [1] to understand the formation of planetesimals from protoplanetary dust, and the structure and physical properties of porous preplanetesimals, we study the influence of high temperature processes on porous dust aggregates. For example, due to internal heating by radioactive decay of short-lived nuclides like
