Resonant absorption in multi-stranded coronal loops
We study the excitation and damping of transverse oscillations in a complex multi-stranded model of a coronal loop. By numerically solving the time-dependent...
Resonant absorption: Transformation of compressive motions into vortical motions
This paper investigates the changes in spatial properties when magnetohydrodynamic (MHD) waves undergo resonant damping in the Alfvén continuum. The analysis is...
Resonantly damped fast MHD kink modes in longitudinally stratified tubes with thick non-uniform transitional layers
Resonantly damped fast kink quasi-modes are computed in fully resistive magnetohydrodynamics (MHD) for two-dimensional equilibrium models. The equilibrium model...
Response functions for the inversion of data from unresolved solar magnetic elements.
By adopting the thin flux tube model as representative of spatially unresolved magnetic elements in the photosphere of the Sun, we identify an adequate set of...
Retrieval of solar magnetic fields from high-spatial resolution filtergraph data: the Imaging Magnetograph eXperiment (IMaX)
Context. The design of modern instruments does not only imply thorough studies of instrumental effects but also a good understanding of the scientific analysis...
Rotating Stars and the Formation of Bipolar Planetary Nebulae. II. Tidal Spin-up
We present new binary stellar evolution models that include the effects of tidal forces, rotation, and magnetic torques with the goal of testing planetary...
Sardinia Radio Telescope observations of Abell 194. The intra-cluster magnetic field power spectrum
Aims: We study the intra-cluster magnetic field in the poor galaxy cluster Abell 194 by complementing radio data, at different frequencies, with data in the...
Scattering Polarization and Hanle Effect in Stellar Atmospheres with Horizontal Inhomogeneities
Scattering of light from an anisotropic source produces linear polarization in spectral lines and in the continuum. In the outer layers of a stellar atmosphere...
Scattering Polarization of Hydrogen Lines in Weakly Magnetized Stellar Atmospheres. I. Formulation and Application to Isothermal Models
Although the spectral lines of hydrogen contain valuable information on the physical properties of a variety of astrophysical plasmas, including the upper solar...
