## Research field

Petr Heinzel's area of research is Solar physics. He has conducted research on solar flares, solar prominences, coronal loops, chromosphere structure and radiative transfer in stellar atmospheres. He has achieved significant scientific contributions in radiation hydrodynamics of stellar atmospheres, as well as in the spectral analysis of astrophysical plasma

## Academic and scientific career

He started working at the Astronomical Institute of AV ČR at Ondřejov after graduating in 1974. There he became the head of the solar department, a position he held until 2004.
From 1987 to 1995, he was associate scientist in the SOHO/SUMER team, that developed a VUV telescope and spectrometer (project SUMER, for Solar Ultraviolet Measurements of Emitted Radiation) at the Max Planck Institute for Solar System Research in Lindau, Germany, to operate on board of the ESA/NASA spacecraft Solar and Heliospheric Observatory (SOHO), which was launched in December 1995
In July 2004, Petr Heinzel became director of the Astronomical Institute of AV ČR. He kept his position in 2007, when the institute was transformed into a public research institution, and remained in office until 2012.
In 2012, Petr Heinzel was appointed Professor of Astronomy and Astrophysics at the Department of Astronomy, Faculty of Mathematics and Physics, Charles University. He had been Associate Professor since 2005.
On 2 April 2017, Petr Heinzel was elected Chair of the Czech Astronomical Society.

## Teacher occupations

Petr Heinzel teaches stellar atmospheres theory and solar physics at Charles University. Abroad, he is an external lecturer at Comenius University in Bratislava, Slovakia and at the University of Wrocław, Poland.
He has been a member of the Supervisory Board for PhD students at Charles University, and a supervisor of PhD students at Charles University, Comenius University, the University of Wrocław, Moscow State University and Cairo University.
He has also been a visiting professor at the Université de Paris (Orsay), Observatoire de Meudon, France, at the University of Wrocław, Poland and at the Max Planck Institute for Astrophysics in Garching, Germany.

## Awards

In 2003, Petr Heinzel received an award from the Czech Academy of Sciences for the analysis of spectral data of hydrogen of the solar atmosphere obtained by the Solar and Heliospheric Observatory (SOHO).
In 2009, he received the Gold Medal of the University of Wrocław for long-term cooperation and in recognition of his scientific results.
Petr Heinzel was laureate for 2014 of the Nušl Prize awarded by the Czech Academy of Sciences. The award was presented by the Chairman of the Czech Astronomical Society of the time Jan Vondrak, Dr Sc.
