    Resonant Absorption in Complicated Plasma Configurations: Applications to Multistranded Coronal Loop Oscillations
    We study the excitation and damping of transverse oscillations in a multistranded model of a straight line-tied coronal loop. The transverse geometry of our...

    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...

    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...
