A 62-minute orbital period black widow binary in a wide hierarchical triple [PDF]
Nature, 2022 Over a dozen millisecond pulsars are ablating low-mass companions in close binary systems. In the original "black widow", the 8-hour orbital period eclipsing pulsar PSR J1959+2048 (PSR B1957+20), high energy emission originating from the pulsar is irradiating and may eventually destroy a low-mass companion.

A puzzling 2-hour X-ray periodicity in the 1.5-hour orbital period black widow PSR J1311−3430
Astronomy & Astrophysics, 2022 Time-domain analysis of an archival XMM-Newton observation unveiled a very unusual variability pattern in the soft X-ray emission of PSR J1311−3430, a black widow millisecond pulsar in a tight binary (PB = 93.8 min) with a very low-mass (M ∼ 0.01 M⊙) He companion star, known to show flaring emission in the optical and in the X-rays.
