We analyze the radiative and nonradiative linearized variables in a gravitytheory within the familiy of the nonprojectable Horava theories, the Horavatheory at the kinetic-conformal point. There is no extra mode in thisformulation, the theory shares the same number of degrees of freedom withgeneral relativity. The large-distance effective action, which is the one weconsider, can be given in a generally-covariant form under asymptotically flatboundary conditions, the Einstein-aether theory under the condition ofhypersurface orthogonality on the aether vector. In the linearized theory wefind that only the transverse-traceless tensorial modes obey a sourced waveequation, as in general relativity. The rest of variables are nonradiative. Theresult is gauge-independent at the level of the linearized theory. For the caseof a weak source, we find that the leading mode in the far zone is exactlyEinstein's quadrupole formula of general relativity, if some coupling constantsare properly identified. There are no monopoles nor dipoles in thisformulation, in distinction to the nonprojectable Horava theory outside thekinetic-conformal point. We also discuss some constraints on the theory arisingfrom the observational bounds on Lorentz-violating theories.
