Nonextensive Effects on Chandrasekhar's Dynamical Friction
J. M. Silva, J. A. S. Lima, R. E. de Souza
The motion of a point like object of mass M passing through the background potential of massive collisionless particles (m << M) suffers a steady deceleration named dynamic frictio…
Lowered Nonextensive Stellar Distribution
J. M. Silva, R. E. de Souza, J. A. S. Lima
The structure of globular clusters and elliptical galaxies are described in an unified way through a new class of lowered models inspired on the nonextensive kinetic theory. These…
Conservative Force Fields in Non-Gaussian Statistics
J. M. Silva, R. Silva, J. A. S. Lima
In this letter, we determine the -distribution function for a gas in the presence of an external field of force described by a potential U(). In the case of a dilute ga…
On the Quintessence Scalar Field Potential
J. A. Espichán Carrillo, J. M. Silva, J. A. S. Lima
In this work we propose a new analytical method for determining the scalar field potential in FRW type cosmologies containing a mixture of perfect fluid plus a quintessence…
