[OA] Antarctic meteorites / Hayabusa


This session is held jointly with Hayabusa 2018 (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.

Conveners : Naoya Imae (NIPR) and Masanao Abe (JAXA)
Note: This session jointly with Hayabusa will be continued to Friday. See also
[I] represents an invited talk.
