Cold uniform spherical collapse revisited
N-body simulations virialization spherical collapse
2010/11/10
We report results of a study of the Newtonian dynamics of N self-gravitating particles which start in a quasiuniform spherical configuration, without initial velocities.
Recently, Sun et al. (2008) published new Galactic 3D-models of magnetic fields in the disk and halo of the Milky Way and the distribution of cosmic-ray electron density by taking into account the the...
PR AND PL (PMV) RELATIONS FOR CLASSICAL CEPHEIDS REVISITED
Cepheids Stars: distances Stars: statistics
2010/10/29
Using observational data available for a large number of Galactic Cepheids, we determine the relation between the radius and the period of pulsations, by means of a variant of the Baade{Wesselink meth...
