From the coma to the nucleus of comet Churyumov-Gerasimenko

Cometary science with data from ROSINA, the Rosetta Spectrometer for Ion and Neutral Analysis

The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) is one of the key scientific instruments on the ROSETTA Orbiter to comet Churyumov-Gerasimenko (CG). The instrument, consisting out of three sensors DFMS, RTOF and COPS, has been designed to answer key questions concerning the origin and formation of comets by measuring neutral gas and the resulting ions originating from a comet. While determining the global molecular, elemental, and isotopic composition in the cometary coma of CG we are interested in characterizing the physical, chemical and morphological character of the cometary nucleus and how this composition impacts the morphology of the nucleus. The ROSINA measurements will be highly instrumental to identify the yet unknown source material for the long-lasting problem of carbon-chain molecules in cometary comae that is seen as a signature of organic material from the formation era of the solar system.

We invite highly motivated PhD students with an excellent Master's degree (M.Sc.) in physics, astrophysics, chemistry or the geosciences to apply for a research project, which will use the unprecedented data set collected by ROSINA and various other instruments on ROSETTA to answer questions related to the cometary activity of comet CG.
