White dwarf pulsar orbits Sun‑like star

Updated: 2026.11.15 35MIN ago 1 sources
Radio surveys (MWA, MeerKAT) have found a repeating radio transient that flashes every ~7.9 minutes and is localized to a binary where the visible companion is a G‑type star like the Sun. Timing and spectral measurements show the pulsing object has about two‑thirds the Sun's mass, implying a white dwarf that behaves like a pulsar — the first such system found around a Sun‑like star. — Expands what astronomers must consider when classifying radio transients, affects models of binary formation and compact‑object behaviour, and changes how unexplained radio signals are framed in public debates about 'alien' signals and survey strategy.

MWA detection of 7.9‑minute flashes, MeerKAT localization to a faint G‑type star, Keck spectroscopy showing minimal stellar wobble, and orbital timing delays yielding a companion mass ~0.67 M☉.
