Outline of Final Research Achievements

This study revealed a time duration of condensation processes of high-temperature dusts formed in the solar protoplanetary disk by high-precision dating of Ca-Al-rich inclusions (CAIs) in meteorites. We measured three high-temperature condensate CAIs and they show a formation age spread of 0.17 ± 0.04 Myr. Our findings demonstrate that both condensation and melting of minerals in a hot nebular gas occurred contemporaneously to form various types of CAIs and continued for at least ~0.2 Myr after the birth of the Solar System.
