Abstract

The exact process of chondrule formation is still not known - common scenarios are formation in a protoplanetary nebular environment: e.g. X-wind model or nebular shock fronts, where precursor grains are heated by collisions with gas.

Most chondrules appear to have been heated to 1500–1600 ºC, followed by a rapid cooling of usually between 10 to 1000 ºC/h.

In this part of our study about the formation of chondrules by shock processes, we try to simulate the formation of chondrules by gas-grain collisions in a nebular environment.
