Simulations of M-type Dwarf Stars
What are M-dwarfs?
Dwarf stars of spectral type M, shortly called “M-dwarfs”, are by far
the most frequent stars in the universe. They are therefore not only
of large interest for our understanding of stars but for a wide range
of topics including the chemical composition and evolution of the
universe and their role as host stars of extra-solar planets. As these
reddish stars are cool and faint, they are relatively difficult to
observe. Consequently, many properties of the atmospheres of these
objects are poorly known yet.
What would be the thesis topic?
Your master thesis project would be closely connected to a study that
recently received funding from the Research Council of Norway. It
focusses on the nature of magnetic fields and chromospheric activity
of M-dwarfs. The approach includes 3-D simulations (radiation
magnetohydrodynamics), spectrum synthesis (radiative transfer
calculations) and comparison with observations (possibly data from
Keck, VLT, Hubble ST).
The exact master thesis project can be defined according to your
interests and abilities. This may involve tasks like carrying out,
analysing, and visualizing 3-D simulations or comparing such data to
observations or a combination of those.
