About The Author

Benz is well known for his observations and interpretation of the solar radio emission and particle acceleration in solar and stellar flares with several hundred scholarly publications. The Güdel-Benz relation between radio and X-ray emission of flares was named after him. More recently, Benz studied star formation using molecular line observations by the Herschel Space Observatory. Benz presided several scientific committees, such as the Swiss Society for Astrophysics and Astronomy (1999-2002) and Division II (Sun and Heliosphere) of the International Astronomical Union (2000-2003).

To the public at large, Benz is known for his numerous presentations on astronomy at the popular level, most prominently on Swiss television and radio since 1979, as well as for his books on the dialog between science and religion. He received an honorary doctorate from the Faculty of Theology of the University of Zurich for his merits to the interaction between science and theology, in which he stresses the differences between scientific and religious perception. The University of the South (Sewanee, TN, USA) awarded him 2017 an honorary doctor's degree in Science "for his distinguished contributions to astronomical inquiry and for his illuminating, interdisciplinary reflections."


Particle Acceleration On The Sun

There are two major enigmas in the outer solar atmosphere, the corona, that have persisted over many decades. Solar flares are explosions above the solar surface that sometimes exceed a hundred times the total energy consumption of all humanity since its existence. Most surprising and not understood is why a significant fraction of the total energy first appears in the form of accelerated electrons and protons, far exceeding terrestrial accelerators in efficiency. And secondly, the corona at the surface is...
