Optical Modulation in the X-Ray Binary 4U 1543-624 Revisited
The X-ray binary 4U 1543-624 has been provisionally identified as an ultra-compact system with an orbital period of ≃ 18 min. We have carried out time-resolved optical imaging of the binary to verify the ultra-short orbital period. Using 140 min of high-cadence r'-band photometry, we recover th...
