Turbulent dynamo in the terrestrial magnetosheath
Zoltán Vörös, Owen Wyn Roberts, Yasuhito Narita +10
Dynamo action refers to energy exchange processes through which magnetic fields are generated at the expense of kinetic energy of the plasma flows. Dynamos can generate magnetic fi…
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…
