Granulation and magnetism in the solar atmosphere.
The properties of the photosphere in magnetic and non magnetic regions, at two levels in the solar atmosphere, have been studied, using two virtually...
Heat transfer in sunspot penumbrae. Origin of dark-cored penumbral filaments
Context: Observations at 0.1 arcsec have revealed the existence of dark cores in the bright filaments of sunspot penumbrae. Expectations are high that such dark...
Heating of the Partially Ionized Solar Chromosphere by Waves in Magnetic Structures
In this paper, we show a “proof of concept” of the heating mechanism of the solar chromosphere due to wave dissipation caused by the effects of partial...
Height Dependence of the Penumbral Fine-scale Structure in the Inner Solar Atmosphere
We studied the physical parameters of the penumbra in a large and fully developed sunspot, one of the largest over the last two solar cycles, by using full...
Height Variation of the Vector Magnetic Field in Solar Spicules
Proving the magnetic configuration of solar spicules has hitherto been difficult due to the lack of spatial resolution and image stability during off-limb...
Heights of formation for measurements of atmospheric parameters.
We argue that heights of formation (HOFs) should not be assigned to spectral lines since a single line my sample very different layers of the atmosphere...
Helioseismic holography of simulated sunspots: dependence of the travel time on magnetic field strength and Wilson depression
Improving methods for determining the subsurface structure of sunspots from their seismic signature requires a better understanding of the interaction of waves...
Standard statistical analysis of the magnetic properties of the quiet Sun rely on simple histograms of quantities inferred from maximum-likelihood estimations...
High frequency generation in the corona: Resonant cavities
Aims: Null points are prominent magnetic field singularities in which the magnetic field strength strongly decreases in very small spatial scales. Around null...
