Clumpy disk accretion and chondrule formation

The process by which chondrules, the largest constituents of primitive meteorites, are formed, is investigated. The thermal mechanism required to convert precursor dust aggregates into chondrules depends on the texture and composition of the chondrules. Shocks inside a nebula are capable of creating chondrules. The shocks may originate from episodic accretion on the solar nebulae of low mass dumps of gas.
