PublicaciónConvectively Driven Sinks and Magnetic Fields in the Quiet-Sun
We study the relation between mesogranular flows, convectively driven sinks and magnetic fields using high spatial resolution spectropolarimetric data acquired...

PublicaciónConverging 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...

PublicaciónCoronal 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...

PublicaciónCoupled 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...

PublicaciónCoupling 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...

PublicaciónDAHe 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...

PublicaciónDamped 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...

PublicaciónDark 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...
