Home Science Center for Astrochemical Studies (CAS) Projects CAS Projects The SOLIS Project The SOLIS (Seeds of Life In Space) project aims to understand how, when and where complex organic molecules form during the early stages of solar-type stars formation. SOLIS is NOEMA large Program. Spectroscopy of Reactive Species We focus here on the high-resolution molecular rotational spectroscopy on highly reactive species that are of astrochemical interest. Optical Characterization of Interstellar Ice Analogs We focus here on the THz and IR optical properties of interstellar ices, and their context in the category of interstellar solids. Low Temperature Collisional Dynamics At low interstellar temperatures, collision dynamics become highly specific to the colliding species and also their internal energy states. These dynamics are hard to predict and model, and rely on laboratory data for benchmarks.
