Upper bounds on the compactness at the innermost light ring of anisotropic horizonless spheres
Yan Peng
In the background of isotropic horizonless spheres, Hod recently provided an analytical proof of a bound on the compactness at the innermost light ring with the dominant energy and…
No short hair behaviors of ultra-compact stars
Yan Peng
In the black hole spacetime, a no short hair theorem was proved, which states that the effective radius of black hole hairs must extend beyond the null circular orbit. In the prese…
Spontaneous scalarization of Gauss-Bonnet black holes surrounded by massive scalar fields
Yan Peng
For massless scalar fields, a relation for was observed in the scalar-Gauss-Bonnet theory. In the present paper, we extend the dis…
Analytical investigations on formations of hairy neutral reflecting shells in the scalar-Gauss-Bonnet gravity
Yan Peng
We study scalarization of spherically symmetric neutral reflecting shells in the scalar-tensor gravity. We consider neutral static massless scalar fields non-minimally coupled to t…
