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...
Numerical simulations of catastrophic collisions of asteroids and fractions of impactor fragments included in remnants
The Japanese spacecraft Hayabusa2 visited the asteroid Ryugu and conducted the detailed proximity observations. The observations show that Ryugu is a rubble...
We present a Monte Carlo model to compute cometary dust tail brightnesses. The model, anologous in many ways to that developed by Fulle (1989, Astron. Astrophys...
Numerical simulations of conversion to Alfvén waves in solar active regions
We study the coupling of magneto-acoustic waves to Alvén waves using 2.5D numerical simulations. In our experiment, a fast magnetoacoustic wave of a given...
