This work is based on Generalized Ghost Pilgrim Dark Energy (GGPDE) in General Relativity (GR) in the framework of Bianchi type V I 0 space-time. To obtain exact solutions of the field equations, we have used simple parametrization of average scale factor a (t) = exp {(αt + β)p } as proposed by Mishra and Dua (Astrophys. Space Sci. ( 2021) 366:6). We have investigated the non-interacting and interacting GGPDE and dark matter (DM). Some well-known parameters like Hubble parameter, equation of state (EOS) parameter, deceleration parameter, etc are constructed for both the models. It is found that deceleration parameter indicates accelerated phase while EOS parameter represents a cosmological constant for both the models. The stability analysis and energy conditions for both the non-interacting and interacting models are investigated.

“…We are also aware of the importance of the theory discussed in this communication. Due to the significance of alternative theories of gravity, many researchers, including our own peer group, have published their research work by considering viable assumptions within scalar tensor theories of gravity [14][15][16][17][18][19][20][21]. Brans-Dicke theory (BDT) holds a significant place in gravitational physics, offering a unique alternative to general relativity (GR) and contributing to our understanding of the cosmos.…”

In the present paper, we have presented the cosmological model in Brans-Dicke theory (BDT) of gravity for a Bianchi type-IX space-time. We obtained the exact solutions of the field equations by applying the new form of deceleration parameter, i.e., FLVDP as proposed by Mishra et al. (2016). In the "Results and Discussion" section, we have also presented the physical and geometric properties and mathematical analysis of the proposed model in Sections 4. Sect. 7 of this communication is equipped with energy conditions and statefinder diagnostic.
