    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...

    Forces on magnetic flux tubes moving in inhomogeneous flows
    The back-reaction of an incompressible two-dimensional flow of constant strain to the accelerated motion of a straight cylinder is calculated in the general...

    Formation and morphology of anomalous solar circular polarization
    Context. The morphology of spectral line polarization is the most valuable observable to investigate the magnetic and dynamic solar atmosphere. However, in...

    Frequency Redistribution Function for the Polarized Two-term Atom
    We present a generalized frequency redistribution function for the polarized two-term atom in an arbitrary magnetic field. This result is derived within a new...

    Full Stokes observations in the He i 1083 nm spectral region covering an M3.2 flare
    We present an exceptional data set acquired with the Vacuum Tower Telescope (Tenerife, Spain) covering the pre-flare, flare, and post-flare stages of an M3.2...

    Further evidence for the presence of a neutron star in 4U 2206+54. INTEGRAL and VLA observations
    The majority of High Mass X-ray Binaries (HMXBs) behave like X-ray pulsars, revealing that they contain a magnetised neutron star. Among the four HMXBs showing...

    G-Band Spectral Synthesis in Solar Magnetic Concentrations
    Narrowband imaging in the G band is commonly used to trace the small magnetic field concentrations of the Sun, although the mechanism that makes them bright has...
