Main building of the former "Sternwarte Babelsberg"

In the Universe, where gravity is ubiquitous, accretion is common. If angular momentum is one of the party, an accretion disk is a requisite to redistribute angular momentum by viscous force. There is a wide variety of disks, ranging from small ones around stellar remnants (black holes, neutron stars, white dwarfs) to protostellar ones and, maybe, to the gaseous star-forming disks in spiral galaxies.

Some publications:

  • The vertical eddy-heat flux as a stabilizer of cold accretion disks (H.-E. Fröhlich and G. Rüdiger, 1999, A&A 343, 348)
