The white dwarf companion of a 2 m☉ neutron star.

BHALERAO V.B. and KULKARNI S.R.

Abstract (from CDS):

We report the optical discovery of the companion to the 2 M☉ millisecond pulsar PSR J1614-2230. The optical colors show that the 0.5 M ☉ companion is a 2.2 Gyr old He-CO white dwarf. We infer that during the accretion phase is. We show that the pulsar was born with a spin close to its current value, well below the rebirth line. The spin-down parameters, the mass of the pulsar, and the age of the system challenge the simple recycling model for the formation of millisecond pulsars.
