The role of the Lorentz force in sunspot equilibrium
J. M. Borrero, A. Pastor Yabar, M. Schmassmann +3
Sunspots survive on the solar surface for time-scales ranging from days to months. This requires them to be in an equilibrium involving magnetic fields and hydrodynamic forces. Unf…
On the contribution of quiet Sun magnetism to solar irradiance variations: Constraints on quiet Sun variability and grand minimum scenarios
M. Rempel
While the quiet Sun magnetic field shows only little variation with the solar cycle, long-term variations cannot be completely ruled out from first principles. We investigate the p…
Extension of the MURaM radiative MHD code for coronal simulations
Matthias Rempel
We present a new version of the MURaM radiative MHD code that allows for simulations spanning from the upper convection zone into the solar corona. We implemented the relevant coro…
Observed and Simulated Power Spectra of Kinetic and Magnetic Energy retrieved with 2D inversions
S. Danilovic, M. Rempel, M. van Noort +1
We try to retrieve the power spectra with certainty to the highest spatial frequencies allowed by current instrumentation. For this, we use 2D inversion code that were able to reco…
Numerical simulations of active region scale flux emergence: From spot formation to decay
M. Rempel, M. C. M Cheung
We present numerical simulations of active region scale flux emergence covering a time span of up to 6 days. Flux emergence is driven by a bottom boundary condition that advects a…
Numerical sunspot models: Robustness of photospheric velocity and magnetic field structure
Matthias Rempel
MHD simulations of sunspots have successfully reproduced many aspects of sunspot fine structure as consequence of magneto convection in inclined magnetic field. We study how global…
