Several years of timing the pulsar in the binary neutron star system M15C have yielded the masses of both stars: the total mass is MT = 2.7121(6) M⊙; the companion mass is mc = 1.36(4) M⊙; and the pulsar mass is mp = 1.35(4) M⊙. We argue that this system is not likely to have formed through accretion-induced collapse (AIC), and that the standard model also has problems in explaining the formation.
