Full text not available from this repository. AbstractContext. During September and October, 2014, OSIRIS cameras onboard ESA Rosetta mission detected millions of single particles. Many of these dust particles appear as long tracks (due to both the dust proper motion and the spacecraft motion during the exposure time) with a clear brightness periodicity.
Aims. We interpret the observed periodic features as a rotational and translational motion of aspherical dust grains.
Methods. Counting the peaks of each track, we obtain statistics of a rotation frequency. We compare these results with the rotational frequency predicted by a model of aspherical dust grain dynamics in a model gas flow. Testing many possible sets of physical conditions and grain characteristics, we constrain the rotational properties of dust grains.
Results. Qualitative and quantitative analysis on the motion of rotating aspherical dust grains with different cross sections in flow conditions corresponding to 67P/Churyumov-Gerasimenko (hereafter 67P/C-G) coma is performed. Based on the OSIRIS observations we constrain the possible phyisical parameters of the grains. | Item URL in elib: | https://elib.dlr.de/97173/ |
