    • Cosmic ray flux at the earth in a variable heliosphere 

      Scherer, K.; Ferreira, S.E.S.; Potgieter, M.S.; Fichtner, H.; Heber, B. (Elsevier, 2008)
      In recent years the variability of the cosmic ray flux has become one of the main issues not only for the interpretation of the abundances of cosmogenic isotopes in cosmochronic archives like, e.g., ice cores, but also for ...
    • A heatwave of accretion energy traced by masers in the G358-MM1 high-mass protostar 

      Burns, R.A.; Chibueze, J.O.; Sugiyama, K.; Hirota, T.; Kim, K.T. (Nature, 2020)
      High-mass stars are thought to accumulate much of their mass via short, infrequent bursts of disk-aided accretion1,2. Such accretion events are rare and difficult to observe directly but are known to drive enhanced maser ...
    • Voyager 2 enters interstellar space 

      Strauss, R. Du Toit (Springer Nature, 2019)
      After 41 years of travel, the Voyager 2 spacecraft joins its twin in interstellar space. A suite of papers report Voyager 2’s experience of its transition through the heliosheath and heliopause to what lies beyond
