Astronomers combined 16.7 years of gamma-ray data with 4.9 years of FAST radio observations to confirm a 3.2-millisecond pulsar has two companions, including a Sun-like star on a 73.5-year orbit
The data confirmed the white-dwarf companion and detected gamma-ray emission associated with the pulsar. More significantly, they uncovered…
