Title:
A rock in the wind - the interaction of comet 67P with the space plasma environment
Host: Maria Hamrin

Abstract:
The Rosetta mission to comet 67P/Churyumov-Gerasimenko has given us a treasure trove of data on the plasma environment around this weakly outgassing comet. In this presentation I will discuss some of the surprising findings by the Rosetta Plasma Consortium, such as “non-classical” magnetic field draping around the nucleus, the singing comet, the diamagnetic cavity and the near-tail region. First an introduction into modern cometary plasma physics will be given, starting at Alfvén and Biermann and the first cometary missions to comet 1P/Halley, before I dive into the more complicated Rosetta data set.

Speaker: Dr. Martin Volwerk, Scientist at the “Institut für Weltraumforschung” of the “Österreichische Akademie der Wissenschaften” in Graz, Austria, working on magnetotail dynamics  using data from the Cluster, DoubleStar and THEMIS spacecraft and on Venus magnetospheric physics using the data from Venus Express, currently working on the Rosette Plasma Consortium data investigating the plasma environment of comet 67P/Churyumov-Gerasimenko.
