title: Chondrule and Planetesimal Formation
abstract: Chondrules are mm-sized silicate-composition abundant spherules in chondritic meteorites. It is considered that they were formed in solar nebula by some heating events, and incorporated in chondritic meteorites. Here, we would like to examine a possible chondrule and planetesimal formation theory; chondrule precursor particles are heated by shock waves produced by earlier generation planetesimals, and later formed planetesimals that have become chondritic parent bodies.
