Advanced Stokes Polarimeter observations are used to study the weakest polarization signals observed in the quiet photosphere with flux densities in the range...
Magnetic topological analysis of coronal bright points
Context. We report on the first of a series of studies on coronal bright points which investigate the physical mechanism that generates these phenomena. Aims...
Magnetic topology of quiet-Sun Ellerman bombs and associated ultraviolet brightenings
Context. Quiet-Sun Ellerman bombs (QSEBs) are small-scale magnetic reconnection events in the lower atmosphere of the quiet Sun. Recent work has shown that a...
The magnetism at the poles is similar to that of the quiet Sun in the sense that no active regions are present there. However, the polar quiet Sun is somewhat...

Magnetic turbulence hidden in the Whirlpool Galaxy
There is a force hidden deep inside galaxies: magnetic fields. Invisible to conventional telescopes, they are a factor in galaxy evolution, regulating the...
Recent observations of the solar atmosphere have provided new insights concerning medium-sized jet phenomena taking place in the solar corona. These jets are...
Magnetism, rotation, and nonthermal emission in cool stars. Average magnetic field measurements in 292 M dwarfs
Stellar dynamos generate magnetic fields that are of fundamental importance to the variability and evolution of Sun-like and low-mass stars, and for the...
Magnetohydrodynamic wave propagation from the subphotosphere to the corona in an arcade-shaped magnetic field with a null point
Aims: The aim of this work is to study the energy transport by means of Magnetohydrodynamic (MHD) waves propagating in quiet-Sun magnetic topology from layers...
