Stellar Rosetta Stone: Accreting White Dwarf Drives Repeating Radio Bursts
TL;DR Summary
An international team using the ASKAP telescope identified ASKAP J1745−5051, a tight white-dwarf–red-dwarf binary that accretes material and emits X‑rays and regular radio bursts every 1.4 hours, pinpointing the source of long-period radio transients and making this system a Rosetta Stone for deciphering these signals and testing extreme physics; future multiwavelength studies are planned.
