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…
A patchy CO exosphere on Ganymede revealed by the James Webb Space Telescope
Dominique Bockelée-Morvan, Olivier Poch, Françcois Leblanc +25
Jupiter's icy moon Ganymede has a tenuous exosphere produced by sputtering and possibly sublimation of water ice. To date, only atomic hydrogen and oxygen have been directly detect…
Spectro-photometry of Phobos simulants: II. Effects of porosity
Antonin Wargnier, Olivier Poch, Giovanni Poggiali +13
Surface porosity has been found to be an important property for small bodies. Some asteroids and comets can exhibit an extremely high surface porosity in the first millimeter layer…
Spectro-photometry of Phobos simulants: I. Detectability of hydrated minerals and organic bands
Antonin Wargnier, Thomas Gautier, Alain Doressoundiram +12
Previous observations of Phobos and Deimos, the moons of Mars, have improved our understanding of these small bodies. However, their formation and composition remain poorly constra…
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…
Identification of Ammonium Salts on Comet 67P/C-G Surface from Infrared VIRTIS/Rosetta Data Based on Laboratory Experiments. Implications and Perspectives
Olivier Poch, Istiqomah Istiqomah, Eric Quirico +29
The nucleus of comet 67P/Churyumov-Gerasimenko exhibits a broad spectral reflectance feature around 3.2 m, which is omnipresent in all spectra of the surface, and whose attribut…
Decimetre-scaled spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
C. Feller, S. Fornasier, P. H. Hasselmann +43
We present the results of the photometric and spectrophotometric properties of the 67P/Churyumov-Gerasimenko nucleus derived with the OSIRIS instrument during the closest fly-by ov…
