Vis-NIR reflectance spectra of a mixture of Magnetite, NH4-Nontronite, Antigonite and Dolomite, pure, mixed with Water ice, during and after ice sublimationStefan Schroeder, Olivier Poch, Marco Ferrari & Simone DeAngelis
This mixture was prepared as a spectral analogue for Ceres surface material. We measured the reflectance spectra (from 0.5 to 4 µm) of the mixture pure (at room temperature) and mixed with water ice particles (at 173 K), as well as during and after sublimation of the water ice under high vacuum (at 173 K). The spectrum of the surface obtained after sublimation exhibits a blue spectral slope.
Vis-NIR bidirectional reflection spectra of several ammonium salts mixed with pyrrhotite grains in sublimate residues at 173 KOlivier Poch & Istiqomah Istiqomah
Dry mixtures (called "sublimate residues") of sub-micrometer size opaque pyrrhotite (Fe1-xS) grains with ammonium (NH4+) salts (chloride, sulfate, formate, carbamate, citrate) were prepared by sublimation of ice-dust mixtures. Reflectance spectra (from 0.4 to 4 µm) of these mixtures were measured at 173 K under high vacuum (pressure lower than 10^-5 mbar).
NIR reflectance spectra of mixtures of AMES tholins with liquid and solid CH4, C2H6 and CH3CN at several temperaturesDaniel Mege, Delphine Nna-Mvondo, Sandeep Singh & Vincent Chevrier
NIR reflectance spectra of AMES tholins (from 90% N2:10% CH4) pure and mixed with different liquids and solids (CH4, C2H6 and CH3CN+C2N6) at temperatures from ambient to 88 K. Spectra were recorded upon cooling while the liquid was progressively added. Freezing occured at some point.

Vis-NIR bidirectional reflection spectra of spherical water ice particles for different sizes (2 to 100 µm), temperatures (173 and 223 K) and temporal evolutionsOlivier Poch, Zuriñe Yoldi & Bernhard Jost
Three types of water ice particles were prepared, having three grain size distributions: 4.5±2.5 µm, 67±31 μm, and between 2 and 100 µm. Reflectance spectra (from 0.4 to 4 µm) of 5mm-deep surfaces of these particles were measured at 173 K, and some at 223 K, under primary vacuum. During time, the particles undergo metamorphism (recristallisation/sintering, change of grains shape and size) and spectra were measured again several hours after the measurement of the fresh...
