Granulation and Convectional Driving on Stellar Surfaces
Johannes Tschernitz, Philippe-A. Bourdin
Surface convection is important for the presence of magnetic activity at stars. So far, this convection is thought to be a result of heating from below, where convection cells rise…
Electromotive field in space and astrophysical plasmas
Philippe-A. Bourdin, Yasuhito Narita
The concept of electromotive field appears in various applications in space and astrophysical plasmas. A review is given on the electromotive field highlighting our current underst…
The Extreme Space Weather Event of 1872 February: Sunspots, Magnetic Disturbance, and Auroral Displays
Hisashi Hayakawa, Edward W. Cliver, Frédéric Clette +19
We review observations of solar activity, geomagnetic variation, and auroral visibility for the extreme geomagnetic storm on 1872 February 4. The extreme storm (referred to here as…
Thaddäus Derfflinger's sunspot observations during 1802-1824: A primary reference to understand the Dalton Minimum
Hisashi Hayakawa, Bruno P. Besser, Tomoya Iju +5
As we are heading towards the next solar cycle, presumably with a relatively small amplitude, it is of significant interest to reconstruct and describe the past grand minima on the…
Driving solar coronal MHD simulations on high-performance computers
Philippe-A. Bourdin
The quality of today's research is often tightly limited to the available computing power and scalability of codes to many processors. For example, tackling the problem of heating…
Application of the electromotive force as a shock front indicator in the inner heliosphere
Bernhard Hofer, Philippe-A. Bourdin
The electromotive force (EMF) describes how the evolution and generation of a large-scale magnetic field is influenced by small-scale turbulence. Recent studies of in-situ measurem…
