We have used deep high-resolution multiband images taken at the ESO Very Large Telescope to identify the optical binary companion to the millisecond pulsar (PSR J1911-5958A) located in the halo of the Galactic globular cluster NGC 6752. The object turns out to be a blue star whose position in the color-magnitude diagram is consistent with the cooling sequence of a low-mass (M ~ 0.17-0.20 M☉), low-metallicity helium white dwarf (He WD) at the cluster distance. This is the second He WD, with this…

TLDR
The color and magnitude of the stellar companion indicate that it is an undermassive white dwarf of age 480 × 106 ± 140 × 106 years, which places a constraint on the recent history of this triple system and supports a scenario in which the current configuration arose through a dynamical exchange interaction in the cluster core.
