The dust in Sauron's eye - Observational and experimental results on the debris disk around HR 4796
M. Bonduelle, J. Milli, O. Poch +14
The optical properties (scattering phase function SPF; degree of linear polarization DoLP; reflectance) of the dust particles orbiting in debris disks can be retrieved through scat…
Insight from laboratory measurements on dust in debris discs
Julien Milli, Olivier Poch, Jean-Baptiste Renard +11
Extreme adaptive optics instruments have revealed exquisite details on debris discs, allowing to extract the optical properties of the dust particles such as the phase function, th…
The polarisation properties of the HD 181327 debris ring. Evidence for sub-micron particles from scattered light observations
Julien Milli, Elodie Choquet, Ryo Tazaki +26
Polarisation is a powerful remote-sensing tool to study the nature of particles scattering the starlight. It is widely used to characterise interplanetary dust particles in the Sol…
Pits on Jupiter Family Comets and the age of cometary surfaces
Aurélie Guilbert-Lepoutre, Selma Benseguane, Laurine Martinien +4
Large and deep depressions, also known as pits, are observed at the surface of all Jupiter Family Comets (JFCs) imaged by spacecraft missions. They offer the opportunity to glimpse…
Cometary dust collected by MIDAS on board Rosetta II. Particle shape descriptors and pristineness evaluation
M. Kim, T. Mannel, J. Lasue +4
The MIDAS (Micro-Imaging Dust Analysis System) atomic force microscope on board the Rosetta comet orbiter investigated and measured the 3D topography of a few hundred nm to tens of…
Chemical and physical properties of cometary dust
Cecile Engrand, Jérémie Lasue, Diane H. Wooden +1
Cometary dust particles are best preserved remnants of the matter present at the onset of the formation of the Solar System. Space missions, telescopic observations and laboratory…
Evolution of pits at the surface of 67P/Churyumov-Gerasimenko
Selma Benseguane, Aurélie Guilbert-Lepoutre, Jérémie Lasue +6
The observation of pits at the surface of comets offers the opportunity to take a glimpse into the properties and the mechanisms that shape a nucleus through cometary activity. If…
Zodiacal light observations and its link with cosmic dust: a review
Jeremie Lasue, Anny-Chantal Levasseur-Regourd, Jean-Baptiste Renard
The zodiacal light is a night-glow mostly visible along the plane of the ecliptic. It represents the background radiation associated with solar light scattered by the tenuous flatt…
Linking studies of tiny meteoroids, zodiacal dust, cometary dust and circumstellar disks
Anny-Chantal Levasseur-Regourd, Clément Baruteau, Jérémie Lasue +2
Tiny meteoroids entering the Earth's atmosphere and inducing meteor showers have long been thought to originate partly from cometary dust. Together with other dust particles, they…
Interpretation through experimental simulations of phase functions revealed by Rosetta in 67P dust coma
Anny-Chantal Levasseur-Regourd, Jean-Baptiste Renard, Edith Hadamcik +3
Context: The dust-brightness phase curves that have been measured by the OSIRIS cameras on board the Rosetta spacecraft within the coma of comet 67P/Churyumov-Gerasimenko (67P) pre…
Flattened loose particles from numerical simulations compared to Rosetta collected particles
Jeremie Lasue, Isabelle Maroger, Robert Botet +5
Cometary dust particles are remnants of the primordial accretion of refractory material that occurred during the initial stages of the Solar System formation. Understanding their p…
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…
The Cassini VIMS archive of Titan: from browse products to global infrared color maps
Stéphane Le Mouélic, Thomas Cornet, Sébastien Rodriguez +11
We have analyzed the complete Visual and Infrared Mapping Spectrometer (VIMS) data archive of Titan. Our objective is to build global surface cartographic products, by combining al…
Retrieval of Water Vapor Column Abundance and Aerosol Properties from ChemCam Passive Sky Spectroscopy
Timothy H. McConnochie, Michael D. Smith, Michael J. Wolff +15
We derive water vapor column abundances and aerosol properties from Mars Science Laboratory (MSL) ChemCam passive mode observations of scattered sky light. Each ChemCam passive sky…
The 67P/Churyumov-Gerasimenko observation campaign in support of the Rosetta mission
C. Snodgrass, M. F. A'Hearn, F. Aceituno +112
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67…
Cosmic dust optical properties: Numerical simulations and future laboratory measurements in microgravity
Jeremie Lasue, Anny-Chantal Levasseur-Regourd
Understanding the properties of particle aggregation and resulting aggregates under microgravity conditions leads to better insights on the formation of the early Solar System plan…
Inferring the interplanetary dust properties from remote observations and simulations
Jeremie Lasue, Anny-Chantal Levasseur-Regourd, Nicolas Fray +1
Since in situ studies and interplanetary dust collections only provide a spatially limited amount of information about the interplanetary dust properties, it is of major importance…
