Abstract We present the relativistic hydrostatic equilibrium equations for a wide class of gravitational theories possessing scalar–tensor representation. It turns out that stellar structure can be written with respect to invariants, allowing interpret their physical role.

We model the dynamical structure of M87 (NGC4486) using high spatial resolution long-slit observations of stellar light in the central regions, two-dimensional stellar light kinematics out to half of the effective radius, and globular cluster velocities out to 8 effective radii. We simultaneously fit for four parameters, black hole mass, dark halo core radius, dark halo circular velocity, and s...

We construct an exact anisotropic star model with a linear barotropic equation of state and Finch-Skea potential within the framework pure Lovelock gravity. A comparison corresponding Einstein in suitable limit is easily deduced. Evidently higher curvature effects induced by contributions generate lower densities, pressures, surface tensions anisotropy factors when compared to its counterpart. ...
