Sometimes They Come Back: Pulsations in A 0538–66 at 69 ms Rediscovered with NICER

We report on Neutron Star Interior Composition Explorer (NICER) X-ray observations of the Be X-ray binary A 0538–66 located in the Large Magellanic Cloud. Fast pulsations (69 ms) in this source were discovered in 1980 during a bright outburst in which it reached a luminosity of ∼8 × 10 ^38 erg s ^−1...
