Recent progress in astrophysical hydromagnetic turbulence is being reviewed. The physical
ideas behind the now widely accepted Goldreich–Sridhar model and its extension to …

Magnetic field generation and evolution in celestial bodies—the subject matter of the theory
of the dynamo—held Ya B Zeldovich's interest for years. Over the time since then, the study …

The formation and evolution of a wide class of astrophysical objects are governed by
turbulent, magnetized accretion disks. Understanding their secular dynamics is of primary …

Aims. We investigate dynamo action in global compressible solar-like convective dynamos
in the framework of mean-field theory. Methods. We simulate a solar-type star in a wedge …

The role of turbulence in various astrophysical settings is reviewed. Among the differences
to laboratory and atmospheric turbulence we highlight the ubiquitous presence of magnetic …

Aims. We study turbulent transport coefficients that describe the evolution of large-scale
magnetic fields in turbulent convection. Methods. We use the test field method, together with …

Aims. The test-field method for computing turbulent transport coefficients from simulations of
hydromagnetic flows is extended to the regime with a magnetohydrodynamic (MHD) …

Вопрос о возникновении и последующей эволюции магнитных полей небесных тел,
составляющий предмет теории динамо, интересовал ЯБ Зельдовича многие годы. За …

Context. A hypothesis for sunspot formation is the buoyant emergence of magnetic flux tubes
created by the strong radial shear at the tachocline. In this scenario, the magnetic field has to …

The existence of large-scale dynamos in rigidly rotating turbulent convection without shear is
studied using three-dimensional numerical simulations of penetrative rotating compressible …
