The analysis of high spectral resolution spectroscopic and spectropolarimetric observations constitutes a very powerful way of inferring the dynamical...
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...
Signature of spin-down stalling in stellar magnetic activity: The case of the open cluster NGC 6811
Context. Stellar rotation and magnetic activity have a complex evolution that reveals multiple regimes. One of the related transitions that is seen in the...
Signatures of the Galactic bar in high-order moments of proper motions measured by Gaia
Our location in the Milky Way provides an exceptional opportunity to gain insight on the galactic evolution processes, and complement the information inferred...
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...
Signs of 'Everything Everywhere All at Once' formation in low-surface-brightness globular-cluster-rich dwarf galaxies
Context. Only two ultra-diffuse galaxies (UDGs) have spatially resolved stellar population properties, showing flat to rising metallicity profiles, indicative...
Silicon in the dayside atmospheres of two ultra-hot Jupiters
Atmospheres of highly irradiated gas giant planets host a large variety of atomic and ionic species. Here we observe the thermal emission spectra of the two...
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...
