In d-dimensional spacetime, strange quark stars gain stability with increasing dimension for ranges of central density, with the mass maximum marking the onset of radial instability, and Newtonian stability holds for adiabatic index at or above 2(d-2)/(d-1).

abstract
We investigate the occurrence and nature of a naked singularity in the gravitational collapse of an inhomogeneous dust cloud described by higher dimensional Tolman-Bondi space-times. The naked singularities are found to be gravitationally strong in the sense of Tipler. Higher dimensions seem to favour black holes rather than naked singularities.

Extra dimensions' influence on the equilibrium and radial stability of strange quark stars
In d-dimensional spacetime, strange quark stars gain stability with increasing dimension for ranges of central density, with the mass maximum marking the onset of radial instability, and Newtonian stability holds for adiabatic index at or above 2(d-2)/(d-1).
