GoKawiilICRAR astronomers find white dwarf orbiting Sun-like star emitting 8-minute radio pulses
Researchers at Curtin University's ICRAR node identified a binary star system, GPM J071507−114153, pairing a white dwarf with a Sun-like G-type star, marking the first detection of radio pulses from such a combination. Previously these periodic radio signals, known as long-period transients, were only seen in systems involving smaller red dwarf stars. Lead author Sam McSweeney said the data, drawn from over 100 hours of observations processed at the Pawsey Supercomputing Research Centre, clearly show the white dwarf's orbital motion, pinpointing the pulses as originating from near or on the white dwarf itself.
