About

Stefan Dreizler is a leading figure in the search for and characterization of exoplanets, with a particular focus on low-mass stars and the detection of small, potentially habitable worlds. His research centers on disentangling the subtle signals of rocky planets from the intrinsic magnetic activity of their host stars, such as spots and faculae. Dreizler’s major contributions include the detection of super-Earths in the temperate zones of M dwarfs, most notably through his work with the HADES and CARMENES collaborations. His 2019 study on Gliese 49, which has garnered over a dozen citations, exemplifies his skill in modeling stellar activity to confirm a super-Earth’s orbit—a critical step in identifying planets where liquid water might exist. Beyond individual discoveries, Dreizler has advanced the methodology for radial velocity planet searches, helping to push the precision needed to find Earth-like planets. His work is foundational for next-generation surveys aiming to characterize the atmospheres of small exoplanets, making him a key researcher in the quest to understand planetary habitability around the galaxy’s most common stars.
