Jun, 2007Citations per year
Abstract: (arXiv)
Spherically symmetric dark energy structures are investigated in the framework of a generalized Chaplygin gas (GCG), which has an equation of state of the form P = - A/\rho^{\alpha}} . We also study these in a modified GCG equation of state, which includes a matter term, i.e. . The results of the latter are then compared with some observational data on low-surface-brightness galaxies which are supposed to be dominated by dark matter.- gas: Chaplygin
