New findings about ions around comets

Sofia Bergman, Swedish Institute of Space Physics (IRF) and Umeå University, will defend her doctoral thesis on low-energy ions around comet 67P/Churyumov-Gerasimenko on 26 November. Observing low energy ions is notoriously difficult because their properties are affected greatly by the spacecraft which observes them. Sofia has developed new methods to do this. Using her work, scientists can study low-energy ions around comets and in a variety of other places in the solar system.
