"Chondrule Formation in Large Scale Shock Waves"

Abstract. Chondrules are small millimeter-sized crystalline spherules found mainly in chondrites - a class of meteorites. From experiments we know that they must have been formed in a high temperature event often referred to as 'chondrule forming event'. The exact mechanism of this event is still unknown and under debate. Among the many proposed scenarios, one suggests the processing of dust in nebular shock waves. I will present a model for processing dust in large-scale shock waves, such as those produced by gravitational instabilities, and I will discuss the consistency with chondrule formation of the resulting temperature history of the dust.
