The large Trans-Neptunian Object 2002 TC from combined stellar occultation, photometry and astrometry data
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +78
On 28th January 2018, the large Trans-Neptunian Object (TNO) 2002TC302 occulted a m15.3 star with ID 130957813463146112 in the Gaia DR2 stellar catalog. 12 positive occultati…
Diurnal variation of dust and gas production in comet 67P/Churyumov-Gerasimenko at the inbound equinox as seen by OSIRIS and VIRTIS-M on board Rosetta
C. Tubiana, G. Rinaldi, C. Güttler +53
On 27 Apr 2015, when 67P/C-G was at 1.76 au from the Sun and moving towards perihelion, the OSIRIS and VIRTIS-M instruments on Rosetta observed the evolving dust and gas coma durin…
ROSETTA/OSIRIS observations of the 67P nucleus during the April 2016 flyby: high-resolution spectrophotometry
C. Feller, S. Fornasier, S. Ferrari +35
In April 2016, the Rosetta spacecraft performed a low-altitude low-phase-angle flyby over the Imhotep-Khepry transition of 67P/Churyumov-Gerasimenko's nucleus. The OSIRIS/Narrow-An…
Tensile Strength of 67P/Churyumov-Gerasimenko Nucleus Material from Overhangs
N. Attree, O. Groussin, L. Jorda +52
We directly measure twenty overhanging cliffs on the surface of comet 67P/Churyumov-Gerasimenko extracted from the latest shape model and estimate the minimum tensile strengths nee…
Constraints on cometary surface evolution derived from a statistical analysis of 67P's topography
J. -B. Vincent, S. F. Hviid, S. Mottola +51
We present a statistical analysis of the distribution of large scale topographic features on comet 67P/Churyumov-Gerasimenko. We observe that the cumulative cliff height distributi…
Seasonal Mass Transfer on the Nucleus of Comet 67P/Chuyumov-Gerasimenko
H. U. Keller, S. Mottola, S. F. Hviid +47
We collect observational evidence that supports the scheme of mass transfer on the nucleus of comet 67P/Churyumov-Gerasimenko. The obliquity of the rotation axis of 67P causes stro…
Distance determination method of dust particles using Rosetta OSIRIS NAC and WAC data
E. Drolshagen, T. Ott, D. Koschny +42
The ESA Rosetta spacecraft has been tracking its target, the Jupiter-family comet 67P/Churyumov-Gerasimenko, in close vicinity for over two years. It hosts the OSIRIS instruments:…
Are fractured cliffs the source of cometary dust jets ? Insights from OSIRIS/Rosetta at 67P
J. -B. Vincent, N. Oklay, M. Pajola +52
Dust jets, i.e. fuzzy collimated streams of cometary material arising from the nucleus, have been observed in-situ on all comets since the Giotto mission flew by comet 1P/Halley in…
Temporal morphological changes in the Imhotep region of comet 67P/Churyumov-Gerasimenko
O. Groussin, H. Sierks, C. Barbieri +45
We report on the first major temporal morphological changes observed on the surface of the nucleus of comet 67P/Churyumov-Gerasimenko, in the smooth terrains of the Imhotep region.…
Comet 67P/Churyumov-Gerasimenko: Constraints on its origin from OSIRIS observations
H. Rickman, S. Marchi, M. F. A'Hearn +12
One of the main aims of the ESA Rosetta mission is to study the origin of the solar system by exploring comet 67P/Churyumov-Gerasimenko at close range. In this paper we discuss the…
Crossing barriers in planetesimal formation: The growth of mm-dust aggregates with large constituent grains
Tim Jankowski, Gerhard Wurm, Thorben Kelling +4
Collisions of mm-size dust aggregates play a crucial role in the early phases of planet formation. We developed a laboratory setup to observe collisions of dust aggregates levitati…
