Ejection speed in the slingshot theory of radio sources. I. Newtonian approximation.
Abstract
The maximum possible ejection velocity of the recoil binary in the slingshot theory of double radio sources is investigated using (1) Newtonian threebody calculations from a survey of 25,000 numerical experiments and (2) a generalrelativistic approximation of the equations of motion. It is shown that although the ejection of a massive binary from a giant elliptical galaxy will occur only if the triple system is relativistic, the Newtonian calculations may be justified for some of the randomly generated threebody examples. The results for these examples demonstrate the possibility of binary ejection in a large variety of triple systems, particularly those in which the orbits are not restricted to a single plane. The generalrelativistic analysis shows that the maximum ejection velocity may be about five times greater than determined with the Newtonian calculations and that each ejection event produces a large flux of gravitational radiation that should be observable in principle. The problem of approximate symmetry in the ejection of double radio sources is considered, and some possible solutions are proposed.
