v 1 1 1 M ay 2 00 6 Charged analogue of Finch - Skea stars
We present solutions to the Einstein-Maxwell system of equations in spherically symmetric gravitational fields for static interior spacetimes with a specified form of the electric field intensity. The condition of pressure isotropy yields three category of solutions. The first category is expressible in terms of elementary functions and does not have an un-charged limit. The second category is ...
متن کاملPair potential of charged colloidal stars.
We report on the construction of colloidal stars: 1 microm polystyrene beads grafted with a dense brush of 1 microm long and 10 nm wide charged semiflexible filamentous viruses. The pair interaction potentials of colloidal stars are measured using an experimental implementation of umbrella sampling, a technique originally developed in computer simulations in order to probe rare events. The infl...
متن کاملCharged Boson Stars and Black Holes
We consider boson stars and black holes in scalar electrodynamics with a V-shaped scalar potential. The boson stars come in two types, having either ball-like or shell-like charge density. We analyze the properties of these solutions and determine their domains of existence. When mass and charge become equal, the space-times develop a throat. The shell-like solutions need not be globally regula...
متن کاملCharged Boson Stars and Vacuum Instabilities
We consider charged boson stars and study their effect on the structure of the vacuum. For very compact particle like “stars”, with constituent mass m∗ close to the Planck mass mP l, i.e. m 2 ∗ = O(αmP l), we argue that there is a limiting total electric charge Zc, which, primarily, is due to the formation of a pion condensate (Zc ≃ 0.5α−1e, where α is the fine structure constant and e is the e...
متن کاملCharged Condensate and Helium Dwarf Stars
White dwarf stars composed of carbon, oxygen or heavier elements are expected to crystallize as they cool down below certain temperatures. Yet, simple arguments suggest that the helium white dwarf cores may not solidify, mostly because of zero-point oscillations of the helium ions that would dissolve the crystalline structure. We argue that the interior of the helium dwarfs may instead form a m...
