A Transition Discovered in the Subcritical Regime of 1A 0535+262
We present NICER observations of the accreting X-ray pulsar 1A 0535+262 during its faint state (≲6 × 10 ^36 erg s ^−1 ), observed in several type I and type II outbursts. We discovered a transition of temporal and spectral properties around the luminosity L _t = 3.3 × 10 ^35 erg s ^−1 , below which...
