The detection of 1.809 MeV gamma-ray line emission from the Vela region by the COMPTEL telescope presents a direct prove of recent nucleosynthesis activity in...
The Cometary Knots in the Helix Nebula have shown themselves to be formed of a head which is a photoionized surface, optically thick to Lyman continuum...
Numerical determination of the modulation transfer function from observations of granulation outside the disk centre.
A spectral ratio, similar to that of von der Lühe (1984), is proposed to derive information on the degradation of the mean granular power spectrum at a position...
Numerical modeling of MHD wave propagation in sunspots: a 3D case
We present the first results of a 3D numerical modeling of linear MHD wave propagation in a realistic sunspot model. In our simulations, a piston located at the...
NUMERICAL SIMULATION OF PROPAGATION AND SCATTERING OF THE MHD WAVES IN SUNSPOTS
We present comparison of numerical simulation results of MHD wave propagation in two different magnitostatic models of sunspots refferred to as "deep" and...
Numerical simulation of propagation of the MHD waves in sunspots
We present results of numerical 3D simulation of propagation of MHD waves in sunspots. We used two self consistent magnetohydrostatic background models of...
