The transition from soluble to insoluble organic matter in interstellar ice analogs and meteorites

Context. Carbonaceous chondrites are sources of information on the origin Solar System. Their organic content is conventionally classified as soluble (SOM) and insoluble matter (IOM), where latter represents majority. Aims. In this work, our objectives to identify possible relations between generated in laboratory experiments extrapolate analog findings meteorites test their connection. Methods. Using experiments, processes possibly linking IOM (IOMA) SOM (SOMA) precursors investigated by assuming that dense molecular ices one Each fraction analyzed laser desorption coupled a Fourier transform ion cyclotron resonance mass spectrometer comprehensive basis. Results. SOMA IOMA significantly differ chemical fingerprints, particularly aromaticity, O/C, N/C elemental ratios. an innovative network, SOMA–IOMA transition was tested, revealing connection both classes. This new network suggests formed two steps: first generation based from SOMA, while second altering generation. Finally, using same analytical technique, Paris compared, showing similarities for time. The application demonstrates related photochemical ice processing present, but overall history formation much more complex might have been affected additional factors (e.g., aqueous alteration). Conclusions. Our approach provides way analyze extraterrestrial material, giving insights into evolution
