Research projects

Potsdam Echelle Polarimetric and Spectroscopic Instrument for the LBT, high-resolution polarimetric spectrograph

The PEPSI Exoplanet Transit Survey is a key science project of the PEPSI spectrograph and investigates the atmospheres of exoplanets, from super-Earths to Hot Jupiters.

A high-resolution survey of TESS target stars near the northern ecliptic pole.

Monitoring of exoplanet host stars with STELLA in order to characterize their starspots and improve the measurements of exoplanet atmospheres.

3D radiation (magneto-) hydrodynamics code designed for the numerical simulation of stellar convection

Stellar Tomography - Zeeman-Doppler-Imaging code for the reconstruction and extrapolation of stellar magnetic fields and temperature distributions.

Robotic telescopes for stellar activity. Instruments are an Echelle spectrograph and a wide-field imaging photometer.

Stellar Activity

A robotic wide-field telescope with a FOV of 50 square degrees to support the PLATO mission

A high-resolution survey of TESS target stars near the northern ecliptic pole.

The STELLA Open Cluster Survey (SOCS) investigates the rotational evolution of cool stars through observations of open clusters with different ages. Precise photometric time series are collected with the STELLA telescope on Teneriffa.

RoboTel is a smaller copy of STELLA. It serves as a robotic test telescope as well as for educational purposes.
