Michael Weber

Dr. Michael Weber serves as Head of the High-resolution Spectroscopy and Polarimetry department at the Leibniz Institute for Astrophysics Potsdam (AIP), where he leads research in astronomical instrumentation and data analysis. His work bridges observational astrophysics and engineering, focusing on spectroscopic and polarimetric techniques for studying celestial objects. He maintains active collaborations across AIP's Stellar Physics, Solar Physics, and Telescope Control divisions.

Weber's research centers on high-resolution spectroscopy and polarimetry, with applications in stellar activity mapping, exoplanet detection, and solar physics. He specializes in designing and operating instruments like the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI), emphasizing time-domain studies of stellar surfaces and magnetic phenomena. His methodology integrates observational data with instrument development to address fundamental questions in stellar evolution.

Analysis of his 11 recent publications (2020-2025) reveals three dominant research threads: (1) Doppler imaging of stellar surfaces (e.g., XX Trianguli, λ Andromedae) to map magnetic activity cycles, (2) instrumentation development for robotic observatories like STELLA and VPNEP surveys, and (3) analysis of stellar phenomena including Betelgeuse's dimming event. These works consistently combine observational astronomy with cutting-edge spectrograph engineering.

As department head, Weber oversees the High-resolution Spectroscopy and Polarimetry group within AIP's Development of Research Technology division. His team operates critical instrumentation for solar and stellar observations, including the Solar Disk Integration Polarimeter and STELLA robotic observatory systems. The department maintains close ties with University of Potsdam through the Astrophysics Network, facilitating instrument development and data analysis pipelines for national and international collaborations.
