Anisotropic stars as ultracompact objects in general relativity
Anisotropic stars as ultracompact objects in general relativity
Anisotropic stresses are ubiquitous in nature, but their modeling in general relativity is poorly understood and frame dependent. We introduce the first study on the dynamical properties of anisotropic self-gravitating fluids in a covariant framework. Our description is particularly useful in the context of tests of the black hole paradigm, …
