Fast MHD oscillations in prominence fine structures
High-resolution observations suggest that quiescent solar prominences are made of small-scale fibrils stacked one after another in both the vertical and...
Fast MHD oscillations of a 3-dimensional prominence fibril
High-resolution observations of quiescent filaments point out that their fine structure is made of small-scale threads or fibrils. These fibrils can be...
Fast-to-Alfvén Mode Conversion in the Presence of Ambipolar Diffusion
It is known that fast magnetohydrodynamic waves partially convert to upward and/or downward propagating Alfvén waves in a stratified atmosphere where Alfvén...
Fast-to-Alfvén Mode Conversion Mediated by Hall Current. II. Application to the Solar Atmosphere
Coupling between fast magnetoacoustic and Alfvén waves can be observed in fully ionized plasmas mediated by stratification and 3D geometrical effects. In Paper...
Feature Extraction Techniques for the Analysis of Spectral Polarization Profiles
This paper introduces a novel feature extraction technique for the analysis of spectral line Stokes profiles. The procedure is based on the use of an...
Field-aligned Evershed flows in the photosphere of a sunspot penumbra
We determine the inclinations of the vector magnetic field and flow velocity in a sunspot penumbra by interpreting full Stokes profiles of three infrared lines...
First observation of bald patches in a filament channel and at a barb endpoint
The 3D magnetic field topology of solar filaments/prominences is strongly debated, because it is not directly measureable in the corona. Among various...
First Observational Evidences for the Presence of Active, Localized Magnetic Structures in White Dwarfs
The magnetic white dwarf WD 1953-011 demonstrates the presence of two-component magnetic field geometry in photosphere. The geometry consists of a weak, large...
Flow and magnetic field properties in the trailing sunspots of active region NOAA 12396
Improved measurements of the photospheric and chromospheric three-dimensional magnetic and flow fields are crucial for a precise determination of the origin and...
