Magnetoacoustic Shocks and Spectropolarimetric Signals in He I 10830 Ã
Hirdesh Kumar, Tobias Felipe, Christoph Kuckein +2
Umbral flashes are manifestations of magnetoacoustic shocks in the solar chromosphere. These phenomena are thought to influence the evolution of chromospheric umbral magnetic field…
Modeling Solar Atmosphere Dynamics with MAGEC
AnamarÃa Navarro, E. Khomenko, N. Vitas +1
Modeling the solar atmosphere is challenging due to its layered structure and multi-scale dynamics. We aim to validate the new radiative MHD code MAGEC, which combines the MANCHA a…
Multi-wavelength spectropolarimetric observations of AR13724 performed by GRIS
C. Quintero Noda, J. C. Trelles Arjona, T. del Pino Alemán +10
Multi-line spectropolarimetric observations allow for the simultaneous inference of the magnetic field at different layers of the solar atmosphere and provide insight into how thes…
Vortex Flows in the Solar Atmosphere: Detection and Heating Mechanisms in 3D MHD Numerical Simulations
M. Koll Pistarini, E. Khomenko, T. Felipe
Vortex flows are structures associated with the rotation of the plasma and/or the magnetic field that are present throughout the solar atmosphere. In recent years, their study has…
Observations of umbral flashes in the resonant sunspot chromosphere
T. Felipe, S. J. González Manrique, D. MartÃnez-Gómez +4
In sunspot umbrae, the core of some chromospheric lines exhibits periodic brightness enhancements known as umbral flashes. The consensus is that they are produced by the upward pro…
