New cosmological tracker solution for quintessence

In this paper we propose a quintessence model with the potential $V\left(\Phi {)=V}_0\right[\sinh \left(\alpha \sqrt{{\kappa }_0}\Delta \Phi \right){]}^{\beta }$ with $\beta <0,$ whose asymptotic behavior corresponds to an inverse power-law potential at early times and to an exponential one at late times. We demonstrate that this is a tracker solution and that it could have driven the Universe into its current inflationary stage. The exact solutions and the description for a complete evolution of the Universe are also given. We compare such a model with current cosmological observations.
