Static and spherically symmetric general relativity solutions in minimal theory of bigravity

We investigate static and spherically symmetric solutions in the Minimal Theory of Bigravity (MTBG). First, we show that a pair Schwarzschild-de Sitter spacetimes with different cosmological constants black hole masses written spatially-flat Gullstrand-Painlev\'e (GP) coordinates is solution self-accelerating branch MTBG, while it cannot be normal branch. then illustrate how can become compatible when using coordinates. also confirm MTBG admits general relativity matter coordinates, including neutron stars arbitrary equations state. Finally, nontrivial are given by metrics nonstandard
