Auswirkungen massereicher Sterne auf ihre Umgebung

Massive stars occur in groups. Stellar evolution reflects how these stars evolve, change their luminosity, shed winds, ionize their environment, and finally explode as supernovae.

Our population synthesis code implements a small set of classical stellar evolution models, and calculates the time histories of stellar luminosities, mass ejections, and nucleosynthesis ejecta.

The thesis task is to implement new/recent stellar evolution models into this code, and evaluate the impact of the different stellar evolution models, comparing these different time histories.

Dynamik der Explosion von Kernkollaps-Supernovae

Supernova explosions are disruptions of stars, and large amounts of gas are ejected into interstellar space. The explosion itself is characterized by matter at high energies characteristic for nuclear fusion, i.e. MeV energies or GK temperatures. The rapid expansion and cooling leaves behind matter that gradually recombines from the original plasma state. Observations across the electromagnetic range thus show matter at different ionization states in characteristic lines, as well as radioactive decay lines.

  The goal of the thesis is to assemble a multi-wavelength picture of the observational constraints on supernova kinematics for the case of Cas A, a nearby SNR from a cc SN ~350 years ago.

Dynamik von Type Ia Supernova-Explosionen

Supernova explosions are disruptions of stars, and large amounts of gas are ejected into interstellar space. The explosion itself is characterized by matter at high energies characteristic for nuclear fusion, i.e. MeV energies or GK temperatures. The rapid expansion and cooling leaves behind matter that gradually recombines from the original plasma state. Observations across the electromagnetic range thus show matter at different ionization states in characteristic lines, as well as radioactive decay lines.

  The goal of the thesis is to assemble a multi-wavelength picture of the observational constraints on supernova kinematics for the case of SN2014J, a recent and nearby SN of type Ia.

Gamma-Strahlen-Spektroskopie: Das Verhalten von Ge Halbleiterdetektoren unter Weltraumbedingungen

    INTEGRAL’s spectrometer SPI features an array of Ge detectors. These record characteristic gamma-rays from many excited nuclei, which are activated by cosmic ray bombardment, or newly produced by those, or are radioactive buildups in a space platform.
    More than 13 years of accumulated data provide a rich database to investigate long-term variations of the line intensities and spectra, which reflect changes in the cosmic ray environment of the spectrometer. A.o., solar activity variations can be investigated here. Expected are unique results of Ge detector performance in space, and about cosmic-ray activation physics in a space orbit. Effects such as the solar activity cycle, and changes in the Earth’s magnetic field configuration, are reflected in these data, and have been prepared for these investigations in an associated master project.
    Interest in data handling is expected (experimental setups, computer-based data manipulations and result assembly). Experience in nuclear physics is advantageous.

Kondensierte Materie

Wenn Atome sich zusammen tun, wird es interessant: Grundlagenforschung an Festkörperelementen, Nanostrukturen und neuen Materialien mit überraschenden Eigenschaften treffen auf innovative Anwendungen.

Kern-, Teilchen-, Astrophysik

Ziel der Forschung ist das Verständnis unserer Welt auf subatomarem Niveau, von den Atomkernen im Zentrum der Atome bis hin zu den elementarsten Bausteinen unserer Welt.

Biophysik

Biologische Systeme, vom Protein bis hin zu lebenden Zellen und deren Verbänden, gehorchen physikalischen Prinzipien. Unser Forschungsbereich Biophysik ist deutschlandweit einer der größten Zusammenschlüsse in diesem Bereich.
