Expanding magnetic canopy structure and parasitic polarities in a quiet-Sun network element observed by Sunrise III/SCIP
Ryan J. Campbell, Carlos Quintero Noda, Mihalis Mathioudakis +44
We present high-resolution multi-line spectropolarimetric observations of a quiet-Sun network element obtained with the {\sc Sunrise~iii} Chromospheric Infrared SpectroPolarimeter.…
Horizontal Magnetic Fields Dominate the Quiet Sun Internetwork in Sunrise III Observations. Evidence from Traditional and Transformer-Based Inversions
Ryan J. Campbell, Carlos Quintero Noda, Manuel Collados +41
The relative prevalence of horizontal and vertical magnetic fields in the quiet-Sun internetwork remains debated, owing to the weak linear polarisation signals that make the inferr…
Fast magneto-acoustic waves in the solar chromosphere: Comparison of single-fluid and two-fluid approximations
M. M. Gómez MÃguez, D. MartÃnez-Gómez, E. Khomenko +3
Context: The mechanism behind the heating of the solar chromosphere remains unclear. Friction between neutrals and charges is expected to contribute to plasma heating in a partiall…
The effect of local magnetic fields in quiet regions of stellar atmospheres simulated with MANCHA
Andrea Perdomo GarcÃa, Nikola Vitas, Elena Khomenko +1
Our aim is to characterize the effects of the local magnetic fields in quiet regions of stellar atmospheres. We compute magneto-hydrodynamic and purely hydrodynamic simulations of…
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…
Convergence study of ambipolar diffusion in realistic simulations of magneto-convection
E. Khomenko, N. Vitas, M. Collados +1
The aim of this paper is to improve our understanding of the heating mechanisms of the solar chromosphere via realistic three-dimensional (3D) modeling of solar magneto-convection,…
