Generalized Papapetrou's equations of motion for an extended test body within static and isotropic metrics
William Almonacid, Leonardo Castañeda
Applying Dixon's general equations of motion for extended bodies, we compute the Papapetrou's equations for an extended test body on static and isotropic metrics. We incorporate th…

The Two Extended Bodies Problem in General Relativity within the post-Newtonian Approximation
William Almonacid
The dynamics of extended bodies is a fundamental problem in any gravitational theory. In the case of General Relativity, this problem is under study since the theory was published.…

Gravitomagnetic effects of a massive and slowly rotating sphere with an equatorial mass current on orbiting test particles
L. Castaneda, F. Fandino, W. Almonacid +2
Within the framework of linearized Einstein field equations we compute the gravito-magnetic effects on a test particle orbiting a slowly rotating, spherical body with a rotating ma…
