Is scalar-tensor gravity consistent with polytropic stellar models?
Kaisa Henttunen, Iiro Vilja
We study the scalar field potential in the scalar-tensor gravity with self-consistent polytropic stellar configurations. Without choosing a particular potential, we numerica…
Consistency of gravity models around solar polytropes
K. Henttunen, I. Vilja
It is stated that a class of gravity models seem to obtain CDM behaviour for high redshifts and general relativistic behaviour locally at high curvatures. In the present…
Stellar configurations in f(R) theories of gravity
K. Henttunen, T. Multamaki, I. Vilja
We study stellar configurations and the space-time around them in metric theories of gravity. In particular, we focus on the polytropic model of the Sun in the $f(R)=R-μ^4/R…
Complex supergravity quintessence models confronted with Sn Ia data
K. Henttunen, T. Multamaki, I. Vilja
A class of supergravity inspired quintessence models is studied by comparing to cosmological data. The set of considered models includes several previously studied quintessential p…
