Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes II. Evidence for coronal emission
M. Marongiu, A. Pellizzoni, S. Righini +43
One of the most important objectives of solar physics is the physical understanding of the solar atmosphere, the structure of which is also described in terms of the density (N) an…
Study of solar brightness profiles in the 18-26 GHz frequency range with INAF radio telescopes I: solar radius
M. Marongiu, A. Pellizzoni, S. Mulas +32
The Sun is an extraordinary workbench, from which several fundamental astronomical parameters can be measured with high precision. Among these parameters, the solar radius $R_{\odo…
The European Solar Telescope
C. Quintero Noda, R. Schlichenmaier, L. R. Bellot Rubio +14
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design…
On the evolution of a sub-C class flare: a showcase for the capabilities of the revamped Catania Solar Telescope
Paolo Romano, Salvo L. Guglielmino, Pierfrancesco Costa +9
Solar flares are occasionally responsible for severe Space Weather events, which can affect space-borne and ground-based infrastructures, endangering anthropic technological activi…
On the formation of a stable penumbra in a region of flux emergence in the Sun
M. Murabito, P. Romano, S. L. Guglielmino +1
We studied the formation of the first penumbral sector around a pore in the following polarity of the Active Region (AR) NOAA 11490. We used a high spatial, spectral, and temporal…
The pre-penumbral magnetic canopy in the solar atmosphere
David MacTaggart, Salvo Guglielmino, Francesca Zuccarello
Penumbrae are the manifestation of magnetoconvection in highly inclined (to the vertical direction) magnetic field. The penumbra of a sunspot tends to form, initially, along the ar…
