Models of the circumstellar medium (CSM) of massive stars can constrain stellar evolution models, since the properties of circumstellar nebulae are like finger prints of the previous evolutionary history of their central stars. Additionally, such models provide the amounts of energy, momentum and of chemical elements which massive stars return into the interstellar medium (ISM), which affect the evolution of star forming galaxies. This project aims particularly at investigating the role and the effects of stellar motion with respect to the ISM with the PLUTO magnetohydrodynamical code. The resulting nebulae are bow-shock with observable characteristics that are determined by both, stellar and ISM parameters.

My master thesis in condensed matter physics (in French) was devoted to quantum transport in nano-electromechanical systems and achieved at the Institut of Physics and Chemistry of Materials in Strasburg (IPCMS) under the supervision of Dr. Dietmar Weinmann and Dr. Guillaume Weick. It consisted in a quantum field approach of electron conduction in a vibrating suspended carbon nano-tube close to the mechanical Euler instability.



This master thesis in astrophysics (in French) was devoted to Quasi-Periodic Oscillations (QPOs) modelling, and led under the supervision of Dr. Jerome Petri at the Astronomical Observatory of Strasburg. This work investigate the possibility of explaining the formation of QPOs in low-mass X-ray binaries via non-linear resonnances into the accretion disk.



I worked summer 2009 with Prof. Dr. Ariane Lancon at the Astronomical Observatory of Strasbourg on a library of stellar near infra-red spectra. I also had the nice opportunity to work summer 2008 with Dr. Bernd Vollmer from the University of Strasburg on the hierarchical galaxies formation model. We exploited the data comming from a numerical simulation in order to test the simulations with respect to the Tully-Fisher law.
