Almost fifty years of Metsähovi solar observations on 37 GHz with recovered digitised historical maps
Sami Kivistö, Frederick Gent, Merja Tornikoski +2
Context. Aalto University Metsähovi Radio Observatory has collected solar intensity maps for over 45 years. Most data coverage is on the 37 GHz frequency band, tracking emissions p…
Numerical evidence for a small-scale dynamo approaching solar magnetic Prandtl numbers
Jörn Warnecke, Maarit J. Korpi-Lagg, Frederick A. Gent +1
Magnetic fields on small scales are ubiquitous in the universe. Though they can often be observed in detail, their generation mechanisms are not fully understood. One possibility i…
Investigating global convective dynamos with mean-field models: full spectrum of turbulent effects required
Jörn Warnecke, Matthias Rheinhardt, Mariangela Viviani +3
The role of turbulent effects for dynamos in the Sun and stars continues to be debated. Mean-field (MF) theory provides a broadly used framework to connect these effects to fundame…
Modelling 3D magnetic networks in a realistic solar atmosphere
Frederick A. Gent, Ben Snow, Viktor Fedun +1
The magnetic network extending from the photosphere (solar radius ) to lower corona ( Mm) plays an important role in the heating mechanisms of the sol…
Sensitivity to luminosity, centrifugal force, and boundary conditions in spherical shell convection
Petri J. Käpylä, Frederick A. Gent, Nigul Olspert +2
We test the sensitivity of hydrodynamic and magnetohydrodynamic turbulent convection simulations with respect to Mach number, thermal and magnetic boundary conditions, and the cent…
Magnetic shocks and substructures excited by torsional Alfvén wave interactions in merging expanding flux tubes
B. Snow, V. Fedun, F. A. Gent +2
Vortex motions are frequently observed on the solar photosphere. These motions may play a key role in the transport of energy and momentum from the lower atmosphere into the upper…
Long-term variations of turbulent transport coefficients in a solar-like convective dynamo simulation
Frederick A. Gent, Maarit J. Käpylä, Jörn Warnecke
The Sun, aside from its eleven year sunspot cycle is additionally subject to long term variation in its activity. In this work we analyse a solar-like convective dynamo simulation,…
Magnetohydrostatic equilibrium. II. Three-dimensional multiple open magnetic flux tubes in the stratified solar atmosphere
Frederick A. Gent, Viktor Fedun, Rebertus Erd'elyi
A system of multiple open magnetic flux tubes spanning the solar photosphere and lower corona is modelled analytically, within a realistic stratified atmosphere subject to solar gr…
Magnetohydrostatic equilibrium. I: Three-dimensional open magnetic flux tube in the stratified solar atmosphere
Frederick Armstrong Gent, Viktor Fedun, Stuart John Mumford +1
A single open magnetic flux tube spanning the solar photosphere (solar radius R) and the lower corona (R + 10 Mm) is modelled in magnetohydrostatic equilibrium within a realistic s…
