Research groups and projects
Magnetohydrodynamics and turbulence
Magnetic fields and turbulence in stars, accretion disks, and galaxies. Computer simulations of dynamos, magnetic instabilities, differential rotation, and magneto-convection; MHD laboratory astrophysics
Physics of the Sun
Determination of the evolution of magnetic structures in the solar atmosphere with optical observations; coronal plasma processes studied by solar radio physics
Stellar physics and stellar activity
Computer simulations of stellar physics such as stellar convection, winds and dust envelopes of red giants; determination of stellar surface parameters and chemical abundances. Observations of stellar activity by robotic doppler imaging and photometry.
