INFERENCES FOR ISOTOPIC FRACTIONATION PROCESSES IN THE SOLAR WIND USING THE FULLSOLAR CYCLE RECORD OF ABUNDANCES FROM ULYSSES:ANTICIPATING RESULTS FROM THE GENESIS MISSION

摘要

On September 8, 2004, during this conference,rnthe mid-air retrieval of the Genesis mission failed,rnand the return capsule crashed into the Utahrndesert sands. Although some important goals ofrnthis mission can probably not be achieved, somernother issues regarding solar wind composition andrnthe solar wind feeding process can be addressedrnand possibly solved. The main purpose of thernGenesis mission is to obtain information on thernisotopic composition of the outer convective zonernof the Sun for as many elements as possible.rnSince it is well known that the solar wind isrnseverely fractionated with respect to the solarrnatmosphere element-wise, it is essential to gatherrninformation on possible isotopic fractionationrnprocesses in order to gain maximum informationrnfrom the Genesis mission. We summarize thernobservational facts and present some inferencesrnfrom theoretical models on isotopic and elementalrnfractionation in the solar wind.
