Göttinger Literaturherbst: Auf der Suche nach den ältesten Sternen (A. Frebel)

Anna Frebel ist der Shootingstar unter den Astrophysikern. Als sie Mitte zwanzig war, mitten in ihrer Promotion, entdeckte sie den bis dato ältesten bekannten Stern. Dass das nicht nur einem Zufall geschuldet war, beweist ihr zweiter Fund kurz darauf: ein noch älterer Stern, etwa 13 Milliarden Jahre alt. Inzwischen ist die „Archäologin der Sterne“ Physikprofessorin am renommierten MIT in Massachusetts. In Göttingen stellt Anna Frebel ihre Arbeit vor, die sie in dem Buch Auf der Suche nach den ältesten Sternen (S. Fischer 2012) anschaulich erklärt. Im Gespräch mit Prof. Sami K. Solanki (Max-Planck-Institut für Sonnensystemforschung) gibt die Wissenschaftlerin einen Einblick in die Entstehung des Universums, der ersten Sterne und berichtet über ihre Arbeit als stellare Archäologin.

MPS Seminar: Observing Cycles, Seasons, and Storms (S.W. McIntosh)

Recent observational findings suggest that the 11(-ish) solar sunspot cycle is a pattern resulting from the interaction, or interference, of large scale magnetic field bands that evolve within the Sun’s convective interior over it’s 22-year magnetic polarity reversal cycle. These toroidal magnetic bands are anchored deep in the solar convection zone and migrate from high latitudes to the equator over 22 years, and new analysis techniques have allowed us to trace their migration from birth to death. We will see that the spatio-temporal interaction of these magnetic bands helps us frame the landmarks of the sunspot cycle with a surprising realization that, once considered, permits a deeper look into the gross energetics of the star, its radiative, particulate and eruptive output and how they vary with time. It is possible that, with refinement and an ongoing commitment to synoptic observational programs, these results offer greatly improved forecast skill on monthly, annual and decadal timescales while a comprehensive physical model can be developed. Finally, we'll think about what observations are required to "close the loop" and drive that modeling effort. [mehr]

MPS Seminar: Nutrient Limitation of the Terrestrial Biosphere: Why should we care? (Sönke Zaehle)

One of Open Science’s visions is to increase the quality and efficiency of scientific research by making research data, computer code, and other resources created in the research process, publicly available. This vision critically depends on the willingness of research groups to share. In this talk we will introduce an ongoing research project of the Junior Research Group ‘Field Specific Forms of Open Science’, that seeks to inform science policy on how field-specific factors influence decisions of researchers to share or not to share. The project employs a multi-method approach including ethnographic field studies, expert interviews, bibliometric mapping, and online surveys in order to examine differences in sharing across research fields in biology, chemistry, and physics. Our particular focus is on how decisions to share are influenced by the way knowledge is produced (the kind of research problems addressed, methods used, the type of empirical objects studied).
