The Eighth Symposium on Polar Science (4 – 8 December 2017)

[OA] Antarctic meteorites / Hayabusa
[OA] 南極隕石 / はやぶさ


This session will be held jointly with Hayabusa 2017 (symposium of solar system material), and to present recent research outcomes for Antarctic meteorites and micrometeorites. It will also be an opportunity for general and topical discussion sessions dealing with new data from non-Antarctic meteorites and extraterrestrial materials, and related experimental and theoretical works.

本セッションは、宇宙物質科学シンポジウム(Hayabusa 2017)と共催します。南極隕石や微隕石からの最新の成果を議論するほか、非南極隕石や地球外物質一般に関するもの、また、関連する実験的、理論的研究に関する発表も歓迎します。

Conveners : Akira Yamaguchi, Naoya Imae (NIPR), and Masanao Abe (JAXA)
Note: This session will be continued to Thursday.
[I] represents an invited talk.
