This paper presents semiempirical models of various solar magnetic structures, extending from the photosphere to the chromosphere. The models have been derived...
Shocks in the Quiet Solar Photosphere: A Rather Common Occurrence
We present observations of the quiet solar photosphere in the Fe I lines at 6302 Å where at least four different spatial locations exhibit upward-directed...
Short-term spectroscopic monitoring of two cool dwarfs with strong magnetic fields
Context: There is now growing evidence that some brown dwarfs (BDs) have very strong magnetic fields, and yet their surface temperatures are so low that the...
Signature of oscillations in coronal bright points
A detailed study of two consecutive bright points observed simultaneously with the Coronal Diagnostic Spectrometer (CDS), the Extreme ultraviolet Imaging...
Signatures of Incomplete Paschen-Back Splitting in the Polarization Profiles of the He I λ10830 Multiplet
We investigate the formation of polarization profiles induced by a magnetic field in the He I multiplet at 10830 Å. Our analysis considers the Zeeman splitting...
Signatures of Magnetic Reconnection at the Footpoints of Fan-shaped Jets on a Light Bridge Driven by Photospheric Convective Motions
Dynamical jets are generally found on light bridges (LBs), which are key to studying sunspot decay. So far, their formation mechanism is not fully understood...
Signatures of the impact of flare-ejected plasma on the photosphere of a sunspot light bridge
Aims: We investigate the properties of a sunspot light bridge, focusing on the changes produced by the impact of a plasma blob ejected from a C-class flare...
Simulated interaction of magnetohydrodynamic shock waves with a complex network-like region
We provide estimates of the wave energy reaching the solar chromosphere and corona in a network-like magnetic field topology, including a coronal null point...
Simulation of a flux emergence event and comparison with observations by Hinode
Aims: We study the observational signature of flux emergence in the photosphere using synthetic data from a 3D MHD simulation of the emergence of a twisted flux...
