# FTheory: Testing the Binary Black Hole Nature of a Compact Binary Coalescence

## Main Content

I will discuss a new way to test the binary black hole (BBH) nature of compact binaries detectable by gravitational wave (GW) interferometers and hence constrain the parameter space of other exotic compact objects. The spirit of the test lies in the "no-hair" conjecture for black holes where all properties of a black hole are characterized by the mass and the spin of the black hole. The proposed method relies on observationally measuring the quadrupole moments of the compact binary constituents induced due to their spins. I will discuss the expected bounds from ground-based and space-based GW detectors.
