Sunspot simulations with MURaM -- I. Parameter study using potential field initial conditions
Markus Schmassmann, Nazaret Bello González, Rolf Schlichenmaier +1
Context. Existing sunspot simulations fail to reproduce the observed magnetic field distribution due to an artificially increased at the upper boundary. Aims. We explore…
Magnetic properties of the umbral boundary during sunspot decay. Comparative study of multiple datasets
M. García-Rivas, J. Jurčák, N. Bello González
The magnetic properties of the umbra-penumbra (UP) boundary of sunspots and the boundary of pores at various evolutionary stages have been characterised using datasets from differe…
Onset of penumbra formation
M. García-Rivas, J. Jurčák, N. Bello González +3
Context. Fully fledged penumbrae have been widely studied both observationally and theoretically. Yet the relatively fast process of penumbra formation has not been studied closely…
Decay of a photospheric transient filament at the boundary of a pore and the chromospheric response
Philip Lindner, Rolf Schlichenmaier, Nazaret Bello González +1
Intermediate stages between pores and sunspots are a rare phenomenon and can manifest with the formation of transient photospheric penumbral-like filaments. Although the magnetic f…
Evolution of the flow field in decaying active regions II. Converging flows at the periphery of naked spots
Hanna Strecker, Nazaret Bello González
In a previous work, we investigated the evolution of the flow field around sunspots during sunspot decay and compared it with the flow field of supergranular cells. The decay of a…
Observations of solar small-scale magnetic flux-sheet emergence
C. E. Fischer, J. M. Borrero, N. Bello González +1
Aims. Moreno-Insertis et al. (2018) recently discovered two types of flux emergence in their numerical simulations: magnetic loops and magnetic sheet emergence. Whereas magnetic lo…
Detection of large acoustic energy flux in the solar atmosphere
N. Bello González, M. Franz, V. Martínez Pillet +9
We study the energy flux carried by acoustic waves excited by convective motions at sub-photospheric levels. The analysis of high-resolution spectropolarimetric data taken with IMa…
