Tracking Quintessence
Artur Alho, Claes Uggla, John Wainwright
Tracking quintessence, in a spatially flat and isotropic space-time with a minimally coupled canonical scalar field and an asymptotically inverse power-law potential $V(φ)\proptoφ^…
Spherically symmetric elastic bodies in general relativity
Artur Alho, José Natário, Paolo Pani +1
The purpose of this review it to present a renewed perspective of the problem of self-gravitating elastic bodies under spherical symmetry. It is also a companion to the papers [Phy…
Scale invariant elastic stars in General Relativity
Artur Alho, José Natário, Paolo Pani +1
We present a model of relativistic elastic stars featuring scale invariance. This implies a linear mass-radius relation and the absence of a maximum mass. The most compact spherica…
Quintessential -attractor inflation: A dynamical systems analysis
Artur Alho, Claes Uggla
The equations for quintessential -attractor inflation with a single scalar field, radiation and matter in a spatially flat FLRW spacetime are recast into a regular dynamical sys…
