Static dilaton space-time parameters from frequency shifts of photons emitted by geodesic particles
Susana Valdez-Alvarado, Ricardo Becerril, Francisco Astorga
The mass parameter of dilaton space-times is obtained as a function of the redshift-blueshift (zred, zblue) of photons emitted by particles orbiting in circular motion around these…

Oscillatons
Susana Valdez-Alvarado, Ricardo Becerril, L. Arturo Urena-Lopez
We solve numerically the Einstein-Klein-Gordon system with spherical symmetry, for a massive real scalar field endowed with a quartic self-interaction potential, and obtain the so-…

Numerical studies of Phi^2-Oscillatons
Miguel Alcubierre, Ricardo Becerril, F. Siddhartha Guzman +3
We present an exhaustive analysis of the numerical evolution of the Einstein-Klein-Gordon equations for the case of a real scalar field endowed with a quadratic self-interaction po…
