M. K. Mak, T. Harko
TL;DR
This paper explores solutions within Brans-Dicke cosmology incorporating a scalar field potential, demonstrating models that align with observations of an accelerating universe from supernova data.
Contribution
It presents three specific solutions of Brans-Dicke theory with a quartic potential and perfect fluid, aligning theoretical models with recent cosmological observations.
Findings
Models exhibit accelerated expansion consistent with supernova data.
Solutions support the viability of scalar-tensor theories in explaining cosmic acceleration.
The behavior of the solutions matches observational constraints on the universe's expansion.
Abstract
Three solutions of the Brans-Dicke theory with a self-interacting quartic potential and perfect fluid distribution are presented for a spatially flat geometry. The physical behavior is consistent with the recent cosmological scenario favored by type Ia supernova observations, indicating an accelerated expansion of the Universe.
