Can rigidly rotating polytropes be sources of the Kerr metric?
J. Martin, A. Molina, E. Ruiz
We use a recent result by Cabezas et al. to build up an approximate solution to the gravitational field created by a rigidly rotating polytrope. We solve the linearized Einstein eq…
An approximate global solution of Einstein's equations for a finite body
J. A. Cabezas, J. Martin-Martin, A. Molina +1
We obtain an approximate global stationary and axisymmetric solution of Einstein's equations which can be considered as a simple star model: a self-gravitating perfect fluid ball w…
Singular sources in the Demianski-Newman spacetimes
V. S. Manko, J. Martin, E. Ruiz
The analysis of singular regions in the NUT solutions carried out in the recent paper (Manko and Ruiz, 2005 Class. Quantum Grav. 22, p.3555) is now extended to the Demianski-Newman…
Limits on Kaluza-Klein Models from COBE Results
Y. Kubyshin, J. Martin
The large-angular-scale anisotropy of the cosmic microwave background radiation in multidimensional cosmological models (Kaluza-Klein models) is studied. Limits on parameters of th…
