In this study, examined are whether the shock waves in the solar nebula are generated by X-ray flares and whether the shock conditions are suitable for chondrule formation. MHD simulations of X-ray flares and subsequent expansion of magnetic bubbles have been conducted, and it was found that shock waves of several tens km/s with velocity could be generated at the upper region of the solar nebula where the gas density is low. Such shock conditions at the upper region of the nebula seem to be appropriate for chondrule formation., 資料番号: AA0047898013}, pages = {49--52}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Shock-wave heating chondrule formation: Generation of shock waves at upper region of solar nebula by X-ray flares and expanding magnetic bubbles}, year = {2004} }
