The objective of the call MSCA Individual Fellows is to enhance the creative and innovative potential of experienced researchers who wish to diversify their individual competence in terms of skill acquisition through advanced training, international and inter-sectorial mobility. Individual Fellowships provide opportunities to acquire and transfer new knowledge and to work on research in a European context or outside Europe. This scheme also supports the return and reintegration of researchers from outside Europe who have previously worked here. It also develops or helps to restart the careers of individual researchers that show great potential, considering their experience.

  • 24 Dec 2013: Merry Christams and a happy New Year from Andreas Quirrenbach: [...] One year ago I wrote that 2013 would be an exciting year for us all. Well, as we know now, the year was a lot more exciting than we had imagined, and a lot more exciting than we would have liked. I thank you all who kept on going with an excellent team spirit in spite of adverse circumstances, which put a lot of strain on our project. We have achieved a number of important milestones, from passing the Final Design Review early in the year to "first calibration light" in Tautenburg very recently. We have received a fair number of parcels containing components and sub-systems, and are looking forward to more shipments and to putting everything together in the coming months. Activities at Calar Alto are also progressing. The coudé room will be prepared for CARMENES as soon as winter weather is behind us, and we expect to install, test, and commission the front end at the telescope in mid-2014. Data reduction software is being written, and our science program is taking shape. With all work packages running in high gear, I am confident that we are on track towards a successful completion of the instrument [...]

The international team estimates that there are tens of billions of such planets in the Milky Way galaxy alone, and probably about one hundred in the Sun's immediate neighbourhood. This is the first direct measurement of the frequency of super-Earths around red dwarfs, which account for 80% of the stars in the Milky Way"
