Accretion of water in carbonaceous chondrites: Current evidence and implications for the delivery of water to early Earth
Protoplanetary disks are dust-rich structures around young stars. The crystalline and
amorphous materials contained within these disks are variably thermally processed and …

The key role of meteorites in the formation of relevant prebiotic molecules in a formamide/water environment
L Rotelli, JM Trigo-Rodríguez, CE Moyano-Cambero… - Scientific reports, 2016 - nature.com
We show that carbonaceous chondrite meteorites actively and selectively catalyze the
formation of relevant prebiotic molecules from formamide in aqueous media. Specific …
