    Converging Flows in the Penumbra of a δ Sunspot
    Doppler velocities in the penumbra of a δ-configuration sunspot observed near the limb indicate flows that converge upon the line separating locally positive...

    Coronal loop oscillations. Calculation of resonantly damped MHD quasi-mode kink oscillations of longitudinally stratified loops
    The observed coronal loop oscillations and their damping are often theoretically described by the use of a very simple coronal loop model, viz. a straight...

    Coupled Fast and Alfvén MHD Waves in Sheared Coronal Arcades
    The magnetohydrodynamic (MHD) normal modes of oscillation of sheared coronal arcades including longitudinal wave propagation are studied. Solutions have been...

    Coupling of fast and Alfvén waves in a straight bounded magnetic field with density stratification
    The theoretical understanding of the linear standing or propagating magnetohydrodynamic waves in a variety of solar coronal structures is far from complete...

    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...
