Pre-accretional irradiation of comet 67P/Churyumov-Gerasimenko constituents
Inès Sansberro, Nicolas Fray, Hervé Cottin +11
Comets are thought to have largely preserved the primordial material from which they formed. Therefore, cometary studies provide important clues about the processes involved in the…
Do twin spectral peaks of olivine particles in the thermal infrared diagnose their sizes and porosities?
Hiroshi Kimura, Johannes Markkanen, Ludmilla Kolokolova +4
A well-established constraint on the size of non-porous olivine grains or the porosity of aggregates consisting of small olivine grains from prominent narrow peaks in thermal infra…
The detection of solid phosphorus and fluorine in the dust from the coma of comet 67P/Churyumov-Gerasimenko
Esko Gardner, Harry J. Lehto, Kirsi Lehto +7
Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Io…
The Morphological, Elastic, and Electric Properties of Dust Aggregates in Comets: A Close Look at COSIMA/Rosetta's Data on Dust in Comet 67P/Churyumov-Gerasimenko
Hiroshi Kimura, Martin Hilchenbach, Sihane Merouane +2
The Cometary Secondary Ion Mass Analyzer (COSIMA) onboard ESA's Rosetta orbiter has revealed that dust particles in the coma of Comet 67P/Churyumov-Gerasimenko are aggregates of sm…
Heliospheric structure as revealed by the 3 -- 88 keV H ENA spectra
A. Czechowski, M. Bzowski, J. M. Sokół +8
Energetic neutral atoms (ENA) are an important tool for investigating the structure of the heliosphere. Recently, it was observed that fluxes of ENAs (with energy 55 keV) com…
The footprint of cometary dust analogues: II. Morphology as a tracer of tensile strength and application to dust collection by the Rosetta spacecraft
L. E. Ellerbroek, B. Gundlach, A. Landeck +6
The structure of cometary dust is a tracer of growth processes in the formation of planetesimals. Instrumentation on board the Rosetta mission to comet 67P/Churyumov- Gerasimenko c…
Synthesis of the Morphological Description of Cometary Dust at Comet 67P
C. Güttler, T. Mannel, A. Rotundi +28
Before Rosetta, the space missions Giotto and Stardust shaped our view on cometary dust, supported by plentiful data from Earth based observations and interplanetary dust particles…
Evidence of sub-surface energy storage in comet 67P from the outburst of 2016 July 3
J. Agarwal, V. Della Corte, P. D. Feldman +67
On 3 July 2016, several instruments on board ESA's Rosetta spacecraft detected signs of an outburst event on comet 67P, at a heliocentric distance of 3.32 AU from the sun, outbound…
The Castalia Mission to Main Belt Comet 133P/Elst-Pizarro
C. Snodgrass, G. H. Jones, H. Boehnhardt +41
We describe Castalia, a proposed mission to rendezvous with a Main Belt Comet (MBC), 133P/Elst-Pizarro. MBCs are a recently discovered population of apparently icy bodies within th…
The footprint of cometary dust analogs: I. Laboratory experiments of low-velocity impacts and comparison with Rosetta data
L. E. Ellerbroek, B. Gundlach, A. Landeck +8
Cometary dust provides a unique window on dust growth mechanisms during the onset of planet formation. Measurements by the Rosetta spacecraft show that the dust in the coma of come…
COSIMA-Rosetta calibration for in-situ characterization of 67P/Churyumov-Gerasimenko cometary inorganic compounds
Harald Krüger, Thomas Stephan, Cécile Engrand +15
COSIMA (COmetary Secondary Ion Mass Analyser) is a time-of-flight secondary ion mass spectrometer (TOF-SIMS) on board the Rosetta space mission. COSIMA has been designed to measure…
Solar wind He pickup ions as source of tens-of-keV/n neutral He atoms observed by the HSTOF/SOHO detector
S. Grzedzielski, P. Swaczyna, A. Czechowski +1
Context. Since 1996, during periods of low solar activity, the HSTOF instrument onboard the SOHO satellite has been measuring weak fluxes of He atoms of 28-58 keV/n (helium energet…
Isotopic Composition of Solar Wind Calcium: First in Situ Measurement by CELIAS/MTOF on Board SOHO
R. Kallenbach, F. M. Ipavich, P. Bochsler +11
We present first results on the Ca isotopic abundances derived from the high resolution Mass Time-of-Flight (MTOF) spectrometer of the charge, element, and isotope analysis system…
