Outgassing of icy bodies in the Solar System - II. Heat transport in dry, porous surface dust layers
Bastian Gundlach, Jürgen Blum
In this work, we present a new model for the heat conductivity of porous dust layers in vacuum, based on an existing solution of the heat transfer equation of single spheres in con…
Experimental investigation of the nebular formation of chondrule rims and the formation of chondrite parent bodies
Eike Beitz, Jürgen Blum, Romain Mathieu +2
We developed an experimental setup to test the hypothesis that accretionary dust rims around chondrules formed in the solar nebula at elevated temperatures. Our experimental method…
The outcome of protoplanetary dust growth: pebbles, boulders, or planetesimals? III. Sedimentation driven coagulation inside the snow-line
A. Zsom, C. W. Ormel, C. P. Dullemond +1
We investigate dust growth due to settling in a 1D vertical column of a protoplanetary disk. It is known from the observed 10 micron feature in disk SEDs, that small micron-sized g…
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…
