The dynamics of a solar arch filament system from the chromosphere to the photosphere
We study the dynamics of plasma along the legs of an arch filament system (AFS) from the chromosphere to the photosphere, observed with high-cadence...
The Dynamics of Buoyant Magnetic Ropes and the Generation of Vorticity in their Periphery
When the Reynolds number is not small, the wake trailing a buoyant magnetic flux tube sheds vortex rolls therefore producing a Von Karman vortex street and an...
The E-ELT first light spectrograph HARMONI: capabilities and modes
HARMONI is the E-ELT's first light visible and near-infrared integral field spectrograph. It will provide four different spatial scales, ranging from coarse...
The new observational O/Fe vs Fe/H relationship in halo dwarfs is analyzed in terms of a model of chemical evolution for the solar neighborhood. The role of...
The Earth as a benchmark: spectro-polarimetry unveils strong bio-signatures
One of the next most important goals of astronomy is the characterization of exo-solar planets and the search for extra terrestrial life. Traditional...
