dc.abstract.enOver a dozen millisecond pulsars are ablating low-mass companions in close binary systems. In the original black widow, the eight-hour orbital period eclipsing pulsar PSR J1959+2048 (PSR B1957+20)<SUP>1</SUP>, high-energy emission originating from the pulsar<SUP>2</SUP> is irradiating and may eventually destroy<SUP>3</SUP> a low-mass companion. These systems are not only physical laboratories that reveal the interesting results of exposing a close companion star to the relativistic energy output of a pulsar, but are also believed to harbour some of the most massive neutron stars<SUP>4</SUP>, allowing for robust tests of the neutron star equation of state. Here we report observations of ZTF J1406+1222, a wide hierarchical triple hosting a 62-minute orbital period black widow candidate, the optical flux of which varies by a factor of more than ten. ZTF J1406+1222 pushes the boundaries of evolutionary models<SUP>5</SUP>, falling below the 80-minute minimum orbital period of hydrogen-rich systems. The wide tertiary companion is a rare low-metallicity cool subdwarf star, and the system has a Galactic halo orbit consistent with passing near the Galactic Centre, making it a probe of formation channels, neutron star kick physics<SUP>6</SUP> and binary evolution.
