Abstract
We revisit the dynamics of a nonminimally coupled scalar field model in case of coupling with , and the potentials , . We use an autonomous system to bring out new asymptotic regimes, and find stable de-Sitter solution. Under the chosen functional form of and steep exponential potentials, a true de-Sitter solution is trivially satisfied for which the equation of state , the effective gravitational constant and field are constant that has been missed in the power law case and our previous study.
