Scalar emission from neutron star-black hole binaries in scalar-tensor theories with kinetic screening
Scalar emission from neutron star-black hole binaries in scalar-tensor theories with kinetic screening
We explore scalar radiation from neutron star-black hole binaries in scalar-tensor theories with kinetic screening ($K$-essence). Using $3+1$ numerical relativity simulations in the decoupling limit, we investigate scalar dipole and quadrupole radiation for different values of the strong coupling constant $\mathrm{\ensuremath{\Lambda}}$. Our results show that kinetic screening effectively suppresses the …
