At the Department of Extrasolar Planets and Atmospheres at the Institute of Planetary Research (Berlin, Germany) photometric time-series data are analyzed to detect and characterize exoplanets (mass, radius etc); also, numerical models are developed to model their light curves, shapes and atmospheres.
Love numbers are measuring the reaction of a celestial body to perturbing forces (e.g. tidal forces, centrifufal rotation). These reactions can be e.g. tidal shape deformation, orbital precession etc. The measurement of polar flattening or orbital precession of exoplanets may constrain the Love numbers and this can open a new dimension in the understanding of the planetary interiors.
Matter Under Planetary Interior Conditions (High Pressure, Planetary, and Plasma Physics ) is a Research Unit located in Rostock, Hamburg, Bayreuth and Berlin (Germany) and funded by the German Research Foundation DFG.
The scope of the Research Unit is aiming at an improved knowledge of the composition and interior structure of planetary interiors through an interdisciplinary approach, involving experiments, theory and modeling activities.
Here, the focus of this PhD work will be on the construction of combined numerical light curve and radial velocity modeling code to measure the polar flattening as well as eccentricity and orbital precession of exoplanets. The results quantity can then be used to give constraints on the Love-number of the exoplanet. The code can be applied to observational data of archive data and of ongoing future satellite missions such as CoRoT, Kepler, K2, TESS, CHEOPS, JWST and PLATO, too. The Research Unit as a whole, will give a particular emphasis on the derivation of scaling laws for exoplanets, relating mass, radius, thermal state, and equilibrium shape as induced by rotational and tidal distortions to each other.
