Observations of a white dwarf/cool star binary that emits from X-ray to radio wavelengths, AR Sco, reveal a close binary with a 3.56-h period, pulsing in brightness with a period of 1.97 min; these pulses are so intense that the optical flux of AR Sco can increase by a factor of four within 30 s, and the pulsing is detectable at radio frequencies.
