Descripción
The results of a 2D numerical simulation of the rise of twisted magnetic flux tubes are sketched. The theoretical criterion for the minimum twist necessary to prevent the conversion of the tube into a pair of strong vortices is shown to be correct. The transition from a low-twist to a high-twist regime is exemplified. There is a sharp transition between the tube interior and the outside medium. A well-developed wake is formed, which however contains only a fraction of the original magnetic flux of the tube.

    A Disc Wind Where You Least Expect It: The Outflow in the Short-period X-ray Binary UW CrB
    Studying outflows of low mass X-ray binaries (LMXBs) is important for understanding the physics of accretion, the evolution of compact binaries, and dynamics of the local interstellar medium. One significant source of these outflows is the accretion disc wind, which can blow away vast amounts of material from the disc before it can be accreted on

    Constraining the core-rotation rate along the red-giant evolution
    The evolution of the core rotation rate of red giant stars is a key parameter in understanding the stellar behavior in the late phases of stellar evolution. Thanks to the mixed-dipole modes, we can constrain the core rotation and internal rotational gradient as a star advances through the red-giant phase. This master thesis presents a pipeline
