Open PhD position to work on exoplanet transit modelling 

Constraining the Love-Number k2,f of Exoplanets

The Institute of Planetary Research in Berlin explores the origin, evolution 
and development of planets, their moons, asteroids and comets of our Solar 
System and other planetary systems. Using spacecraft and earth-based remote 
sensing techniques, laboratory experiments, in-situ investigations and 
numerical modelling, the institute is well established within the national 
and international research community and industry.

At the Department of Extrasolar Planets and Atmospheres photometric 
time-series data are analyzed to detect and characterize exoplanets (mass, 
radius etc.) and their atmospheres; also, numerical models are developed to 
model their light curves and atmospheres.

The measurement of polar flattening of exoplanets and constraints on the 
Love-number 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 new Research Unit located in Rostock, Hamburg, Bayreuth 
and Berlin (Germany) and funded by the German Research Foundation. 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 work will be on the construction of numerical light 
curve modeling code to measure the polar flattening of exoplanets and its 
applications to publicly available space-photometric light curves (CoRoT, 
Kepler, K2). The measured flattening quantity is then used to give 
constraints on the Love-number of the exoplanet. The code can be applied to 
observational data of future satellite missions such as CHEOPS 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.

It is expected that this position leads to the completion of a PhD.

Applications should be sent by 20 June 2017. Earliest starting date is 1 
September 2017. Please attach up to two letters of reference, CV, motivation 
letter to your application.
