AGB stars and their dust grains in the solar system

Giovedì 4 febbraio alle ore 15:00, la dr. Nan Liu della Washington University, St. Louis (US), terrà il web-seminar dal titolo: AGB Stars and Their Dust Grains in the Solar System.

 

Abstract

Presolar grains found in pristine meteorites are stellar relics that predate our solar system. They enable the study of bona fide stellar materials in the laboratory, where the full battery of modern micro-analytical techniques can be brought to bear on them. In this talk, I will present isotopic compositions of presolar SiC grains from low-mass asymptotic giant branch (AGB) stars obtained in laboratory and discuss the implications to low-mass AGB stellar evolution and nucleosynthesis.

Web-seminar ad accesso riservato.
