Oxygen isotopic heterogeneity in the early Solar System inherited from the protosolar molecular cloud
The Sun is (16)O-enriched (Δ(17)O = −28.4 ± 3.6‰) relative to the terrestrial planets, asteroids, and chondrules (−7‰ < Δ(17)O < 3‰). Ca,Al-rich inclusions (CAIs), the oldest Solar System solids, approach the Sun’s Δ(17)O. Ultraviolet CO self-shielding resulting in formation of (16)O-rich CO a...
