Planetary migration in evolving planetesimals discs
S. Yesilyurt, A. Del Popolo, N. Ercan
In the current paper, we further improved the model for the migration of planets introduced in Del Popolo et al. (2001) and extended to time-dependent planetesimal accretion disks…
Evolution of planetesimal discs and planets migration
A. Del Popolo, S. Yesilyurt, N. Ercan
In this paper, we further develop the model for the migration of planets introduced in Del Popolo, Gambera and Ercan, and extended to time-dependent planetesimal accretion disks in…
Dark matter, density perturbations and structure formation
A. Del Popolo
This paper provides a review of the variants of dark matter (CDM, HDM) which are thought to be fundamental components of the universe and their role in origin and evolution of stru…
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…
Non-local bias and the problem of large-scale power in the Standard Cold Dark Matter model
A. Del Popolo, Y. Takahashi, H. Kiuchi +1
We study the effect of non-radial motions, originating from the gravitational interaction of the quadrupole moment of a protogalaxy with the tidal field of the matter of the neighb…
The statistics of the gravitational field arising from an inhomogenous system of particles
A. Del Popolo, M. Gambera, x
In this paper we extend Chandrasekhar and von Neumann's analysis of the statistics of the gravitational field to systems in which particles (e.g. stars, galaxies) are not homogeneo…
