    DAHe white dwarfs from the DESI Survey
    A new class of white dwarfs, dubbed DAHe, that present Zeeman-split Balmer lines in emission has recently emerged. However, the physical origin of these...

    Damped oscillations of two interacting coronal loops
    We present results on the oscillatory properties (periods, damping rates, and spatial distribution of perturbations) for resonantly damped oscillations in a...

    Dark Matter, Magnetic Fields, and the Rotation Curve of the Milky Way
    The study of the disk rotation curve of our Galaxy at large distances provides an interesting scenario for us to test whether magnetic fields should be...

    Deep probing of the photospheric sunspot penumbra: no evidence of field-free gaps
    Context. Some models for the topology of the magnetic field in sunspot penumbrae predict regions free of magnetic fields or with only dynamically weak fields in...

    DeSIRe: Departure coefficient aided Stokes Inversion based on Response functions
    Future ground-based telescopes, such as the 4-metre class facilities DKIST and EST, will dramatically improve on current capabilities for simultaneous multi...

    Detailed processes accompanying the decay of an active region.
    High resolution (better than 1arcsec) magnetograms obtained at the Sacramento Peak Vacuum Tower Telescope were used to study the decay of a small active region...

    Detection of a Peculiar Drift in the Nuclear Radio Jet of the TeV Blazar Markarian 501
    Mrk 501 is one of the most prominent TeV-emitting blazars and belongs to the class of high synchrotron peaked (HSP) blazars. The Doppler factors derived from...

    Detection of emission in the Si I 1082.7 nm line core in sunspot umbrae
    Context. Determining empirical atmospheric models for the solar chromosphere is difficult since it requires the observation and analysis of spectral lines that...

    Detection of Polarization from the E4Π-A4Π System of FeH in Sunspot Spectra
    Here we report the first detection of polarization signals induced by the Zeeman effect in spectral lines of the E4Π-A4Π system of FeH located around 1.6 μm...
