Dust release and tensile strength of the non-volatile layer of cometary nuclei
Yuri Skorov, Jürgen Blum
We developed a thermophysical model for cometary nuclei, which is based upon the assumption that comets form by the gravitational instability of an ensemble of dust and ice aggrega…
Outgassing of icy bodies in the solar system - I. The sublimation of hexagonal water ice through dust layers
Bastian Gundlach, Yuri Skorov, Jürgen Blum
Our knowledge about the physical processes determining the activity of comets were mainly influenced by several extremely successful space missions, the predictions of theoretical…
Activity of comets: Gas Transport in the Near-Surface Porous Layers of a Cometary Nucleus
Yu. Skorov, R. van Lieshout, J. Blum +1
The gas transport through non-volatile random porous media is investigated numerically. We extend our previous research of the transport of molecules inside the uppermost layer of…
Thermal conductivity measurements of porous dust aggregates: I. Technique, model and first results
Maya Krause, Jürgen Blum, Yuri V. Skorov +1
We present a non-invasive technique for measuring the thermal conductivity of fragile and sensitive materials. In the context of planet formation research, the investigation of the…
