英文摘要
We investigated the formation of dust in the ejecta of supernovae that are considered to be sources of interstellar dust in the early universe. Then we studied the evolution of the newly formed dust in the shocked gas within the supernova remnants and revealed the size distribution and mass of the dust injected into the interstellar medium. Based on the results of these calculations, we estimated UV-optical extinction curves expected in the early universe. We also demonstrated how the formation process of dust depends on the type of supernovae through the varying thickness of their outer envelopes.
