Dynamics of the rise of magnetic flux tubes in stellar interiors
In sonnenähnlichen Sternen erhält ein Dynamo-Mechanismus die Magnetfelder. Der Babcock-Leighton-Dynamo beruht auf einem solchen Mechanismus und erfordert insbesondere die Existenz von magnetischen Flussröhren. Man nimmt an, dass magnetische Flussröhren am Boden der Konvetionszone entstehen und …

Shear instabilities in stellar objects: linear stability and non-linear evolution
… objects, including accretion discs and stellar interiors. Due to observational limitations the complex dynamics in stellar interiors that result in turbulent motions, mixing processes, and magnetic field generation, are not entirely understood. It is therefore necessary to investigate …

Layer-layer interactions in atmospheric, cryospheric, and stellar dynamics
… mechanics, and turbulence in velocity-layered stellar interiors. Three distinct manifestations of stratosphere-troposphere coupling are studied in this dissertation. First, evidence suggests that ozone depletion has driven changes in southern hemisphere tropical tropospheric width, motivating …

Time-Domain Astrophysics with the Transiting Exoplanet Survey Satellite
… are useful for other science cases, ranging from stellar astrophysics to transient science. This thesis focuses on using TESS to study both the circumstellar environment and stellar interiors, as well as using the satellite to detect and characterize optical emission from gamma-ray bursts (GRBs). …

Magnetic fields and stellar oscillations
… With sufficiently precise photometry, stellar oscillations can be detected through the periodic variations they induce in a star's brightness. Understanding the connection between the internal structure of a star and the properties of its normal modes is the focus of stellar oscillation …

Path integral Monte Carlo and the electron gas
… a host of real systems, from simple medals to stellar interiors. However, its most common use is as input into density functional theory. To this end, we aim to build an accurate representation of the electron gas from the ground state to the classical limit and examine its use in …

Exploring Machine Learning, Feature Engineering, and Explainability to Constrain Spica’s Apsidal Constant through MESA Simulations
… of Virgo and offers valuable insights into stellar interiors and dynamics. Within binary systems, gravitational forces between the two stars cause minor distortions that alter their orbital motion. The steady rate of this alteration is known as the apsidal constant, which provides key …
