title: New frontier of chronology of the Solar Syetem based on the in-situ absolute dating
abstract: Constraining the timescales for the evolution of planetary bodies in our solar system is essential for a complete understanding of planet-forming processes. However, frequent collisions between planetesimals in the early Solar System obscured and destroyed much of the primitive features of the old, first-generation planetary bodies. The in-situ absolute dating which I have been developing, enables us to decipher such a veiled history of the Solar System. In seminar, I will talk about our new findings.
