Thomas K. Henning (born 9 April 1956) is a German astrophysicist. Since 2001, he is a director at the Max Planck Institute for Astronomy. Henning is an expert in the field of star and planet formation. Education and career Henning studied physics and mathematics at the University of Greifswald, specializing in plasma physics. He continued his studies at the University of Jena, specializing in astronomy and astrophysics and obtaining his PhD in 1984. After joining Charles University in Prague as a postdoc (1984–1985), Henning returned to Jena where he served as an assistant at Jena Observatory, completing his habilitation in 1989. He then became a guest scientist at the Max Planck Institute for Radio Astronomy in Bonn 1989–1990 and a guest lecturer at the University of Cologne in 1991. Henning returned to the University of Jena that same year, taking over as managing scientist of the Max Planck Research Unit "Dust in Star-Forming Regions", a post he held until 1996. Henning became a professor at Jena University in 1992. In 1999, Henning became Chair of Astrophysics at Jena University; a position he was to hold until 2002. At the same time, he became Director of the Astrophysical Institute and of Jena Observatory. Thomas Hennung served as a guest professor at the University of Amsterdam. the European Southern Observatory in Chile, at Sapporo University and the University of Copenhagen. Between 2000 and 2007, he was co-chair of the DFG research group "Laboratory Astrophysics" in Chemnitz and Jena. Since 2001, Henning is a director and scientific member at the Max Planck Institute for Astronomy, where he is head of the planetary and star formation department. He retains his professorship at Jena and, in 2003, joined the faculty at Heidelberg University as an honorary professor. Work Henning works in the field of star and planet formation. One of his areas of specialization is the observation and modelling of protoplanetary disks around young stars – an early stage in the evolution of planetary systems. To this end, Henning has also done research on the properties of interstellar dust and, more generally, on the physics and chemistry of the interstellar medium – both theoretically and using the methods of laboratory astrophysics and observational astronomy. The focus of his observational work is at infrared and submillimeter wavelengths. Throughout his career, Henning was and is involved in a number of major research projects, including the construction of
