Oxygen isotopic anomaly and solar nebular photochemistry

Letter to the Editor


At the cool periphery of the solar nebula, oxygen could photochemically be formed from water. The mixing of17O and18O enriched by the self-shielding effect of16O2 to the dust grain melted by the shock waves there would explain the oxygen isotopic anomaly in the high-temperature mineral of the carbonaceous meteorites.
