Johannes Löhner-Böttcher

Dr. Johannes Löhner-Böttcher is a Postdoctoral Fellow in the High Altitude Observatory (HAO) of NCAR. His scientific research focuses on the systematic physical processes which dominate the lower solar atmosphere.

By observing the Sun with various ground-based and space-borne solar telescopes and their spectropolarimetric instruments, he studies the magnetic activity, convective motions, and wave phenomena in the solar photosphere and chromosphere. Dr. Löhner-Böttcher is further involved in the development of additional calibration methods for spectropolarimetric data (e.g., of the upcoming in-house instruments ChroMag and ViSP). Beyond, he is interested in the exoplanet detection by radial velocity measurements, and their improvement by transferring our in-depth knowledge about the Sun to other stars.

Before joining HAO, Dr. Löhner-Böttcher worked as a Postdoctoral Fellow at the Kiepenheuer Institute for Solar Physics (KIS) in Freiburg, Germany. As an Instrument Scientist for the Laser Absolute Reference Spectrograph (LARS), he performed high-accuracy solar spectroscopy operating a laser frequency comb at the Vacuum Tower Telescope (VTT) at the Teide Observatory on Tenerife, Spain.

Dr. Löhner-Böttcher received his PhD in Physics in 2016 from the University of Freiburg, Germany. His work on “Wave phenomena in sunspots” was awarded with magna cum laude. Before, he studied mathematics and physics at the University of Erlangen-Nürnberg and the University of Freiburg, where he graduated with his state examination thesis about “Flow fields around sunspots” at the Kiepenheuer Institute for Solar Physics.
