Strange xenon in Jupiter

Jupiter's helium-rich atmosphere contains xenon with excess¹³⁶Xe and the ratio of r-products more closely resembles “strange” xenon (Xe-X, alias Xe-HL) seen in carbonaceous chondrites than xenon seen in the solar wind (SW-Xe). The linkage of primordial helium with Xe-X, as seen on a microscopic scale in meteorites, apparently extended across planetary distances in the solar nebula, This is expected if the solar system acquired its present chemical and isotopic diversity directly from debris of the star that produced our elements.
