A three-dimensional model for the radio emission of magnetic chemically peculiar stars
C. Trigilio, P. Leto, G. Umana +2
In this paper we present a three-dimensional numerical model for the radio emission of Magnetic Chemically Peculiar stars, on the hypothesis that energetic electrons emit by the gy…
Non radial motions and the shapes and the abundance of clusters of galaxies
A. Del Popolo, M. Gambera
We study the effect of non-radial motions on the mass function, the velocity dispersion function (hereafter VDF) and on the shape of clusters of galaxies using the model introduced…
Tidal torques and the clusters of galaxies evolution
A. Del Popolo, M. Gambera
We study the effect of tidal torques on the collapse of density peaks through the equations of motion of a shell of barionic matter falling into the central regions of a cluster of…
The influence of dynamical friction on the collapse of spherical density pertubation
A. Del Popolo, M. Gambera, V. Antonuccio-Delogu
We solve numerically the equations of motion for the collapse of a shell of baryonic matter falling into the central regions of a cluster of galaxies, taking into account of the pr…
