Abstract
We compute the emission of gravitational waves of white dwarf dynamical interactions and close encounters in dense stellar environments and we compare it with the sensitivity curves of planned space-borne gravitational wave detectors, like eLISA and ALIA. We find that for the three possible outcomes of these interactions—which are the formation of an eccentric binary system, a lateral collision in which several mass transfer episodes occur, and a direct one in which just a single mass transfer episode takes place—only those in which an eccentric binary are formed are likely to be detected by the planned gravitational wave mission eLISA, while ALIA would be able to detect the gravitational wave signal emitted in lateral collisions.
