Low-phase spectral reflectance and equivalent geometric albedo of meteorites powders

Pierre Beck, Bernard Schmitt, Sandra Potin +2

The reflectance of a particulate surface depends on the phase angle at which it is observed. This is true for laboratory measurements on powders of natural materials as well as rem…

Ammonium salts are a reservoir of nitrogen on a cometary nucleus and possibly on some asteroids

O. Poch, I. Istiqomah, E. Quirico +29

The measured nitrogen-to-carbon ratio in comets is lower than for the Sun, a discrepancy which could be alleviated if there is an unknown reservoir of nitrogen in comets. The nucle…

SHADOWS: a spectro-gonio radiometer for bidirectional reflectance studies of dark meteorites and terrestrial analogs: design, calibrations, and performances on challenging surfaces

S. Potin, O. Brissaud, P. Beck +5

We have developed a new spectro-gonio radiometer, SHADOWS, to study in the laboratory the bidirectional reflectance distribution function of dark and precious samples. The instrume…

Laboratory simulations of the Vis-NIR spectra of comet 67P using sub-μm sized cosmochemical analogues

Batiste Rousseau, Stéphane Érard, Pierre Beck +15

Laboratory spectral measurements of relevant analogue materials were performed in the framework of the Rosetta mission in order to explain the surface spectral properties of comet…

Radiative transfer model for contaminated slabs : experimental validations

François Andrieu, Frédéric Schmidt, Bernard Schmitt +2

This article presents a set of spectro-goniometric measurements of different water ice samples and the comparison with an approximated radiative transfer model. The experiments wer…
