Dark Matter and Charged Exotic Dust
Dark matter charged dust isothermal Lane-Emden equation
2011/10/18
The density profiles of dark matter halos are often modeled by an approximate solution to the isothermal Lane-Emden equation with suitable boundary conditions at the origin. It is shown here that such...
Nonlinear instability of wormholes supported by exotic dust and a magnetic field
wormholes supported exotic dust magnetic field
2010/3/17
Recently, spherically symmetric, static wormholes supported by exotic dust and a radial magnetic field have been derived and argued to be stable with respect to linear radial fluctuations. In this rep...
