Solar Research

The provided text includes information about solar research. Richard R. Fisher completed construction of a photoelectric coronal photometer at Sacramento Peak and began observations of the 530.3 nm line at several heights above the limb. These observations were taken over by Richard Altrock and continued to 2015, when the 16" John W. Evans coronagraph was mothballed. Coronal rain is known to be one of the highest resolution tracers of the coronal magnetic field.

Solar-Stellar Connection

As the era of super-high resolution solar astronomy approaches, it is worth considering the current state of the so-called Solar-Stellar Connection, and its future prospects. The Kepler mission, for example, has multiplied, by thousands, the number of stars with high-quality asteroseismology. Chandra and XMM-Newton together have obtained X-ray luminosities and energy distributions of many dozens of solar-type stars, some "quiet" like the Sun, but others at the extreme upper limits of activity. A main message from the stellar side is that solar high-energy phenomena fall at the low end of the broad spectrum of behavior seen among the stars; but all along that ladder are seen the conspicuous signatures of strong dynamics, likely inspired by impulsive energy releases on small spatial scales.

Penumbra Formation

Fully-fledged penumbrae are a well characterised phenomenon from an observational point of view. Also, MHD simulations reproduce the observed characteristics and provide us with insights on the physical mechanisms possibly running behind the observed processes. The sole cause necessary for penumbral magneto-convection is a stably inclined magnetic field. Observations show that inclined fields can be caused by flux emergence, to form orphan penumbrae, or by field lines dragged down from upper photospheric layers, to form sunspot penumbra.

Chromospheric Studies

The newly installed instrument at the Swedish 1-m Solar Telescope, CHROMIS, allows us to investigate the chromosphere by observing Ca H & K lines using a narrow-band-filter. The resonance lines of Ca II are formed in the chromosphere, where their formation are strongly influenced by departures from LTE (non-LTE effects), horizontal radiative transfer (3D effects), and partially-coherent scattering of photons (PRD effects). In this talk, we will present results from multi-line and multi-atom non-LTE chromospheric inversions in solar active regions. We combine data observed with ground-based instrumentation (CRISP/CHROMIS) and from the IRIS satellite.

Interferometric BIdimensional Spectro-polarimeter (IBIS)

The Interferometric BIdimensional Spectro-polarimeter (IBIS) is a dual Fabry-Perot system built by INAF/Arcetri Observatory. Installed at the DST since 2003, it has been employed in a variety of scientific studies by a large international audience. Indeed, its high spectral stability, good image quality, multi-line capabilities, ease-of-use, and versatility have made of IBIS a valued instrument for both photospheric and chromospheric physics, as well as further-reaching subjects such as planetary physics.

European Solar Telescope (EST)

With first light expected in 2026, the European Solar Telescope (EST) represents the most important technological joint effort made by the ground-based European Solar Physics community. EST will improve considerably the present European observational capabilities thanks to its 4-meter diameter. Its optical design is especially designed to study magnetic phenomena taking place in the solar atmosphere, optimising two crucial aspects.

Visible SpectroPolarimeter ViSP for DKIST

The Visible SpectroPolarimeter ViSP for DKIST is a flexible research spectropolarimeter. It is capable of simultaneous observations of polarized light in 3 spectral regions between 380 and 900 nm, at high spatial and spectral resolution.

Kappa-Distributions in Solar Corona

The presence of the kappa-distributions or distributions exhibiting high-energy tails in the solar corona and transition region can be expected due to particle acceleration processes arising as a result of heating by nanoflares and associated short term particle acceleration processes. These non-Maxwellian distributions affect the ionization, recombination, and excitation rates.
