The recent advances in astrophysical observations, and the gravitational wave observations, in particular, offer the long waited opportunities to test the strong field regime of gravity. For this purpose, though, it is very important to study the full spectrum of solutions in a variety of modified theories of gravity, including the more complicated case of (rapid) rotation. Our talk focuses on a variety of solutions describing compact objects in ones of the most natural and widely used alternatives to Einstein’s theory, namely the (extended) scalar-tensor theories. We will discuss some of the astrophysical implication of these objects as well and the prospects of using them to further test the strong field regime of gravity.
