内容記述 | Evaporation during chondrule melting may have resulted in depletion of volatile elements in chondrules. However, no evidence for a large degree of heavy-isotope enrichment has been reported in chondrules. In order to meet this observed constraint, the rapid heating rate at temperatures in a temperature range from FeS eutectic (1,273 K) to silicate solidus (1,573 K) is required. Numerically simulated was the chondrule formation with shock-wave heating model including the radiative transfer among dust particles. It has been found that if the preshock region is optically thin for the thermal continuum emission from dust particles, the shock-wave heating mechanism meets the high heating rate constraint, because the dust thermal emission does not keep the dust particles high temperature for a long time in the preshock region. In such a case, the dust particles are abruptly heated by the gas drag heating behind the shock front. | |||||
