Workshop Astronomie am Fallturm

ZARM - Raum 1730; Am Fallturm, 28359 Bremen

"Astronomie am Fallturm" aims to give an insight into space science and space technologies for Bachelor- and Master's students and is open to the public. To strenghen comprehensibility, the talks are chaired and the audience has the possibility to discuss the topic without professors before asking questions about the talk. Workshop language is German.

Programm:
14:00-14:30 Vorbesprechung der Vorträge mit
Dr. Farid Gamgami (OHB System AG, Bremen) 
und Dr. Marco Scharringhausen (DLR Bremen)

Begrüßung und Anmoderation des ersten Vortrags
Prof. Dr. Claus Lämmerzahl (ZARM, University Bremen)

14:30-15:30 Prof. Dr. Jürgen Schmitt
(Hamburg Observatory, University Hamburg):
"Warum und zu welchem Ende studieren wir die Aktivität von Sonne und Sternen?"
Abstract: Eine weitgefächerte Phänomenologie beschreibt die Aktivitätseigenschaften der Sonne, die sich über das gesamte elektromagnetische Spektrum vom Radiobereich bis hin in den Gamma-Bereich nachweisen lassen.  Alle Aktivitätsindikatoren variieren im  11-Jahresrhythmus des Sonnenfleckenzyklus und legen einen letztendlich magnetischen Ursprung nahe. Als Ursache der magnetischen Aktivität der Sonne wird ein magnetischer  Dynamo angenommen, der tief im Sonneninnern neues Magnetfeld erzeugt, das durch magnetischen Auftrieb an die Oberfläche gelangt und dort beobachtbar wird.  Es stellt sich die offensichtliche Frage, inwieweit ähnliche Prozesse auf anderen Sternen stattfinden, inwieweit die Sonne ein typisches Verhalten aufweist, und welche Stellarparameter die Stärke der beobachteten Stellaraktivität kontrollieren.
Im Vortrag werden die verschiedenen zum Studium stellarer Aktivität verwendeten Methoden diskutiert und die zentralen Ergebnisse und Erkenntnisse der letzten Dekaden u.a. im Hinblick auf extrasolare Planeten vorgestellt.

Begrüßung und Anmoderation des ersten Vortrags durch Prof. Dr. Claus Lämmerzahl (ZARM, University Bremen)

14:30-15:30 Prof. Dr. Ulrich Geppert (DLR Bremen): "Pulsare und Magnetare: Elektromagnetische Interaktionen innerhalb und außerhalb von Neutronensternen"
Abstract: Neutronensterne sind ganz besondere Sterne im Weltall: Sie besitzen unter allen Sternen die größte Diche, die höchsten Temperaturen. die kürzesten Umdrehungszeiten und die stärksten Magnetfelder. In meinem Vortrag werde ich einen allgemeinverständlichen Überblick über die Physik der Neutronensterne geben. Ganz szpeziell werde ich dabei auf die höchst faszinierenden Magnetare eingehen, die nochmal ganz besondere Neutronensterne sind.

16:30-17:30 Dr. Elke Roediger (Hamburg Observatory, University Hamburg): "Dynamische Galaxienhaufen"
Abstract: Auf großen Skalen, jenseits von mehreren Millionen Lichtjahren, ist das Universum vom "kosmischen Netz" durchzogen. Gravitation lässt Materie entlang von Filamenten kollabieren. An den Knotenpunkten des Netzes befinden sich Galaxienhaufen, Ansammlungen von hunderten oder mehr Galaxien. Den weit größeren Anteil baryonischer (normaler) Materie steuert jedoch das dünne, heisse Haufengas bei, welches den Raum zwischen den Galaxien füllt. Haufengas und Galaxien werden vom Halo dunkler Materie zusammengehalten. Galaxienhaufen sind noch in der "Wachstumsphase". Galaxien und Galaxiengruppen fallen in bestehende Haufen ein; Kollisionen zwischen Galaxienhaufen gehören zu den energiereichsten Ereignissen im Universum. Jets von super-massereichen schwarze Löchern im Zentrum von Galaxienhaufen heizen das Haufengas. Der Vortrag wird ein Überblick über Beobachtungen und theoretische Untersuchungen der dynamischen Vorgänge in Galaxienhaufen geben.
