Laboratory Experiments to Understand Comets

Olivier Poch, Antoine Pommerol, Nicolas Fray +1

In order to understand the origin and evolution of comets, one must decipher the processes that formed and processed cometary ice and dust. Cometary materials have diverse physical…

Reflection, emission, and polarization properties of surfaces made of hyperfine grains, and implications for the nature of primitive small bodies

Robin Sultana, Olivier Poch, Pierre Beck +8

There are various indications that the most primitive small bodies (P, D-type asteroids, comets) have surfaces made of intimate mixtures of opaque minerals and other components (si…

Reflectance study of ice and Mars soil simulant associations -- I. HO ice

Zuriñe Yoldi, Antoine Pommerol, Olivier Poch +1

The reflectance of water ice and dust mixtures depends, amongst other parameters, on how the components are mixed (e.g. intimate mixture, areal mixture or coating) (Clark et al. 19…

Reflectance study of ice and Mars soil simulant associations -- II. CO and HO ice

Zuriñe Yoldi, Antoine Pommerol, Olivier Poch +1

We measure the visible and near-infrared reflectance of icy analogues of the Martian surface made of CO ice associated in different ways with HO ice and the regolith simula…

Biosignatures of the Earth I. Airborne spectropolarimetric detection of photosynthetic life

C. H. Lucas Patty, Jonas G. Kühn, Petar H. Lambrev +10

Context. Homochirality is a generic and unique property of life on Earth and is considered a universal and agnostic biosignature. Homochirality induces fractional circular polariza…

Origins of colors variability among C-cluster main-belt asteroids

Pierre Beck, Olivier Poch

The Sloan Digital Sky Survey provides colors for more than 100 000 moving objects, among which around 10 000 have albedos determined. Here we combined colors and albedo in order to…
