We consider magnetohydrodynamics models and observations of transverse oscillations in prominence threads to obtain information on their physical properties...

We investigate the diagnostic potential of polarimetric measurements with filtergraph instruments. Numerical simulations are used to explore the possibility of...

Direct measurements of plasma motions are limited to the line-of-sight component at the Sun's surface. Multiple tracking and inversion methods were developed to...

Spectral energy distributions (SEDs) encode information about the stellar populations within galaxies. By investigating the properties of these stars, such as...

One of the most useful spectral windows for spectropolarimetric investigations of the solar chromosphere is the one provided by the spectral lines of the He I...

Recent high-resolution observations have pointed out that prominences are made of small threads (also named fibrils) piled up to form the body of the prominence...

The Sun's convective envelope generates, by dynamo effect, a surface magnetic field whose strength evolves on an 11-year cycle, with a change in polarity at the...

The He I triplet at 10830 Å has a great potential for determining the magnetic field vector in the upper chromosphere. The triplet is Zeeman sensitive (Landé...
