Zusammenfassung/Abstract:The Sun releases its thermonuclear energy not only in form of the well know and a seemingly constant flow of white light but also by a highly variable stream of non-visible electromagnetic radiation, by plasma flows and energetic particles. Altogether these energy flows form the external environmental conditions for the planet Earth now called the "Space Weather". The Space Weather conditions are highly variable - even more than the atmospheric weather conditions. The reason is that the sources of the Space Weather are eruptive energy releases from the Sun with the most prominent Solar Flares and called Coronal Mass Ejections (CMEs). The increasing social relevance of the Space Weather conditions has recently led to intensive efforts to understand of the reason of solar eruptions. We present the main existing models of solar eruptions as they actually are under development and demonstrate their verification by means of numerical simulations directly comparable with solar observations. We further compare these findings with the results of current laboratory eruption experiments carried out at the Princeton Plasma Physics Laboratory (MRX).

From darkness to light – the emergence of star clusters from molecular clouds

Lupe

Dr. James Dale
(Universitäts-Sternwarte München, Ludwig-Maximilians-Universität)
Dienstag/Tuesday, 2015-11-24 14:00 c.t., Raum EW-114
Eugene-Paul-Wigner Gebäude, Hardenbergstr. 36, 10623 Berlin

Zusammenfassung/Abstract:

The most important stage of a star cluster’s life is that in which it emerges from the molecular cloud in which it formed, and becomes optically visible. Over a short timescale, residual gas is expelled from the cluster, the remains of the cloud are dispersed, star formation is terminated, and the embedded stellar population, previously visible only in the infrared, becomes optically bright. I will present numerical simulations of this complex process, compare them with the latest observational results and discuss the implications of the current state of this field for the global star formation process.

Modelling the stellar winds from hot and cool stars

NGC 7635 (The Bubble Nebula) - A strong stellar wind and intense radiation from a star has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud.

Eugene-Paul-Wigner Gebäude, Hardenbergstr. 36, 10623 Berlin

Zusammenfassung/Abstract:
Mass loss from massive stars is very important for determining their evolution and death, but their wind properties can be difficult to measure and are often very uncertain.

Main sequence massive stars have fast and highly ionized winds, driving bubbles in their surroundings that have proven surprisingly difficult to detect. We have run simulations showing that wind bubbles are typically very asymmetric and do not fill their HII regions.

Coalescence of intermediate-mass black holes: Implications for GW Astronomy

Dr. Pau Amaro-Seoane
(AEI Potsdam-Golm)
Freitag/Friday, 2014-12-05, 14:00 c.t., EW 561
Eugene-Paul-Wigner Gebäude, Hardenbergstr. 36, 10623 Berlin

Zusammenfassung/Abstract:
Observations suggest that star clusters often form in binaries or larger bound groups. Therefore, mergers between two clusters are likely to occur. If these clusters both harbour an intermediate-mass black hole (IMBH; ~100-10,000 M$_\odot$) in their center, they can become a strong source of gravitational waves when the black holes merge with each other.

Hinweise zu Verlegungen von Vorlesungen

  • Raumänderung: die Übungen zu Grundlagen der Astronomie und Astrophysik, am Freitag von 10-12 Uhr, finden nicht mehr im Raum ER 164 statt, sondern im Raum EW 809/10, und die Übung am Donnerstag von 16-18 Uhr findet ab sofort im Raum EW 226 statt.
  • Der Beginn der Vorlesung Turbulenz für Astrophysiker und des Seminars Numerische Simulationsmethoden sind noch offen. Für weitere Information kontaktieren Sie bitte den Dozenten (Wolf.Mueller<at>ipp.mpg.de).
