ABSTRACT Neutron stars receive velocity kicks at birth in supernovae. Those formed electron-capture supernovae from superasymptotic giant branch – the lowest mass to end their lives may significantly lower than typical neutron stars. Given that many massive are members of wide binaries, this suggests existence a population low-mass (1.25 < Mpsr/M⊙ 1.3), (Porb ≳ 104 d), eccentric (e ∼ 0.7...
