Nitrogen isotopes in the recent solar wind: Further analysis of gold-plated concentrator frame from Genesis

Creators

Abstract

Nitrogen, the fifth most abundant element in the universe, displays the largest (after H) stable isotope variations in the solar system materials (excluding pre-solar grains). Recently several studies concluded that protosolar nebula N was depleted by ~400‰, from (i) the combined ion probe analysis of H and N isotopes in lunar soil grains (δ^(15)N ≤240‰, [1]), (ii) the analysis of the Jupiter atmosphere by either infrared spectroscopy [2] or in situ by the Galileo probe [3] and (iii) δ^(15)N of 400‰ for osbornite (TiN) embedded in a CAI [4]. The Genesis mission sampled solar wind ions during 27 months in space by passive implantation of SW ions in targets made of pure material. Despite a hard landing of the sample capsule, target material could be recovered and analyzed.
