Abstract
The seven Galactic double neutron stars (DNS)s exhibit a relation between the pulsar spin period and the orbital eccentricity. We show that this relation can only be produced if the second neutron star received a kick that is substantially smaller (with a velocity dispersion of less than 50 km s-1) than the standard kick received by a single radio pulsar. This demonstrates that the kick mechanism depends on the evolutionary history of the NS progenitor and that the orbital parameters of DNSs are completely determined by the evolution in the preceding helium star - neutron star phase.
