Tidal flows in extrasolar planets and stars

This PhD research project investigates tidal flows inside extrasolar planets and stars to understand the mechanisms by which they dissipate. Since 1995, astronomers have discovered thousands of extrasolar planets, many of which are hot Jupiters that orbit their host stars very closely. Gravitational tidal interactions between these planets and their stars can determine orbital characteristics and internal rotations. The project aims to understand tidal flows using computer simulations and theoretical calculations, examining the effects of rotation, stratification, convection, and magnetic fields on fluid dynamics and magnetohydrodynamics in stars and planetary fluid layers. The research will be conducted at the University of Leeds, which hosts one of the leading groups in Astrophysical and Geophysical Fluid Dynamics. The group is actively engaged in research on planetary and extrasolar planetary dynamics, solar and stellar dynamics, and galactic dynamics. This 3.5-year PhD position offers comprehensive training and support in applied mathematics and astrophysical fluid dynamics.
