Context. Outgassing of dust-ice aggregates plays an important role on the surfaces of
cometary nuclei as well as for snow-line crossings in protoplanetary disks. Aims. To assess …

This paper presents a new approach to determining the dimensions of particles that can be
lifted to a coma by the sublimation flux of water ice. Due to the diverse colour of the cometary …

We show that if comets (or any small icy planetesimals such as Kuiper belt objects) are
composed of pebble piles, their internal radiogenic as well as geochemical heating results …

The paper presents experimental studies on the degassing of porous ice and porous
mixtures of ice and sand in a vacuum. The study aims to find the relationship between the …

In this paper we presented the results of laboratory experiments dealing with the sliding of
desiccated sand on the inclined surfaces of cometary analogs. The experiments were …

A profound understanding of gas flow in porous media is of great interest for various
technological and scientific fields. Its investigation by laboratory measurements, however …

During the first stages of planet formation, the collision growth of dust aggregates in
protoplanetary discs (PPDs) is interrupted at the bouncing barrier. Dust aggregates coated …

We report on the widespread occurence of talus on cerean crater walls using Dawn framing
camera images. This is unexpected for a planetary body with no atmosphere like Ceres …

The paper presents the results of spectroscopic measurements for selected dust analogues,
based on which change in cometary brightness was determined. In the first part of the article …

A heating event in a protoplanetary disk could sublimate H 2 O ice from icy aggregates. After
the heating event, the temperature decreased, and the H 2 O vapor recondensed to form …
