Abstract

For a given Lovelock order NN, it turns out that static fluid solutions of the pure Lovelock equation for a star interior have the universal behavior in all n2N+2n\geq 2N+2 dimensions relative to an appropriately defined variable and the Vaidya-Tikekar parameter KK, indicating deviation from sphericity of 33-space geometry. We employ the Buchdahl metric ansatz which encompasses almost all the known physically acceptable models including in particular the Vaidya-Tikekar and Finch-Skea. Further for a given star radius, the constant density star, always described by the Schwarzschild interior solution, defines the most compact state of distribution while the other end is marked by the Finch-Skea model, and all the other physically tenable models lie in between these two limiting distributions.
