Aqueous alteration without initial water: possibility of organic-induced hydration of anhydrous silicates in meteorite parent bodies oleh Naoki Hirakawa, Yoko Kebukawa, Yoshihiro Furukawa, Masashi Kondo, Hideyuki Nakano, Kensei Kobayashi

"…Water formed through decomposition of organic matter could be one candidate for hydrous silicate formation, for example, in ordinary chondrites from S-type asteroids inside the H2O snow line. Although the origin of water in ordinary chondrites is under debate, water generation from organic matter may also explain the D-rich water in ordinary chondrites because primordial organic matter is known to be D rich.…"

Meteorites and the RNA World: Synthesis of Nucleobases in Carbonaceous Planetesimals and the Role of Initial Volatile Content oleh Klaus Paschek, Dmitry A. Semenov, Ben K. D. Pearce, Kevin Lange, Thomas K. Henning, Ralph E. Pudritz

"…The synthesis of prebiotic organic matter in carbonaceous asteroids could be well explained by a combination of (i) radiogenic heating, (ii) aqueous chemistry involving a few key processes at a specific range of radii inside planetesimals where water can exist in the liquid phase, and (iii) a reduced initial volatile content (H _2 , CO, $\mathrm{HCN}$ , and CH _2 O) of the protoplanetary disk material in the parent body region compared to the outer region of comets.…"
