Our speaker Jérome Gattacceca from CEREGE in Aix-en-Provence joins us for the first Seminar of the new academic year.
Our The Earth currently accretes 60 000 tons of extraterrestrial material every year in the form of meteorites, micrometeorites and nanometric “dust”.
These materials are rather well characterized but their flux, and hence their delivery mechanism that reflects the dynamics of the Solar System bodies, is less well constrained.
Based on meteorite and micrometeorite collections from the Atacama desert and Antarctica, Jérome will discuss what we know about the intensity and composition of this flux, and their possible variation with time.
Coffee and tea will be available after the seminar in the first floor foyer of the Williamson Building.
