Amides from the carbonaceous asteroid (162173) Ryugu: nanoscale spectral and isotopic characterizations
L. G. Vacher, V. T. H. Phan, L. Bonal +5
C-type asteroids, such as asteroid (162173) Ryugu, may have played a key role in delivering light elements to early Earth. Nitrogen (N)-bearing molecules have been chemically ident…

Polarimetry of Water Ice Particles Providing Insights on Grain Size and Degree of Sintering on Icy Planetary Surfaces
Olivier Poch, Romain Cerubini, Antoine Pommerol +2
The polarimetry of the light scattered by planetary surfaces is a powerful tool to provide constraints on their microstructure. To improve the interpretation of polarimetric data f…
