Abstract

We study the black hole solution and gravitational wave polarizations in a M-subset of the Einstein-aether theory with Lorentz invariance violated by an unit norm vector field -- the aether field uau^a. This M-subset of Einstein-aether theory has a form of Einstein-Maxwell theory with a term of Lagrange multiplier potential λ(uaua1)\lambda(u_au^a\mp1). When the aether field is timelike or spacelike, there exists a static solution -- DD-dimensional Reissner-Nordstrom form of black hole solution, in which the aether charge have a minimum and maximum values. This conception of the aether charge doesn't exist in the cic_i subset of the Einstein-aether theory. The Smarr formula and the first law can be exactly constructed via the extended method of Killing potential. For the linearized M-subset Einstein-aether theory with the timelike aether field, we find the speed of spin-2 modes is unit, which aren't dependent on spacetime dimensions DD and aether constant b1b_1, but some parts of polarizations are disappeared. The speed of spin-1 modes is unit also. The third kind mode is the longitudinal aether-metric mode, which is linearly time dependent and not the spin-0 mode reported in the cic_i subset Einstein-aether theory.
