In 2026, Kovi Rose traced a 1.3-hour radio pulse and matching X-ray flicker to ASKAP J1745-5051, a white-dwarf system so tight that the orbit itself appears to become the clock

ASKAP J1745-5051 pulses in radio light every 1.345 hours, and its X-rays flicker on nearly the same clock. That clock is not the spin of a solitary neutron star. In a Nature Astronomy paper published on June 1, 2026, Kovi Rose and colleagues identify the source as an accreting white dwarf binary, a compact pair […]
