    On the Scaling of the Damping Time for Resonantly Damped Oscillations in Coronal Loops
    There is not as yet full agreement on the mechanism that causes the rapid damping of the oscillations observed by TRACE in coronal loops. It has been suggested...

    On the sensitivity of the Halpha scattering polarization to chromospheric magnetism
    A particularly interesting line for exploring the physical conditions of the quiet solar chromosphere is Halpha , but its intensity profile is magnetically...

    On the Sr I λ4607 Å Hanle depolarization signals in the quiet Sun
    The Hanle depolarization signals of Sr i λ4607 Å have been used to estimate the unsigned magnetic flux and magnetic energy existing in the quiet Sun photosphere...

    On the Stokes V Amplitude Ratio as an Indicator of the Field Strength in the Solar Internetwork
    The results of the determination of magnetic field strength from weak polarimetric signals in solar internetwork regions are contradictory. We investigate the...

    On the theory of MAG waves and a comparison with sunspot observations from CDS/SoHO
    We examine the influence of non-adiabatic effects on the modes of an isothermal stratified magnetic atmosphere. We present new solutions for magneto-acoustic...

    On the validity of quasi-linear kinematic mean-field electrodynamics in astrophysical flows
    Mean-field theory in its kinematic form with the quasi-linear approximation is widely used for the modelling of the transport of weak magnetic fields in...

    Optical counterpart of the XTE J0929-314 in quiescence: constraints on the magnetic field
    We present VLT observations of the optical counterpart of th X-ray millisecond pulsar XTE J0929-314 in quiescence. We detected a very faint candidate in...
