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
✦AI Summary
Astronomers have identified the source of a mysterious 1.3-hour radio pulse as an accreting white dwarf binary system named ASKAP J1745-5051. This discovery helps clarify the nature of long-period radio transients that previously defied standard pulsar models.
Why it matters
This finding provides a crucial data point for understanding stellar evolution and the behavior of compact binary systems in deep space.
ASKAP J1745-5051 pulses in radio light every 1.345 hours, and its X-rays flicker on nearly the same clock.
