A newly discovered pulsar, spinning 220 times per second, has been found orbiting its companion in what astronomers describe as one of the most circular orbits ever measured. The object was detected by China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST) and lies in the plane of the Milky Way.
The dead star's near-flawless orbit suggests a stable, billion-year relationship between the two celestial bodies. Such a precise circular path is rare and provides a valuable record of the system's evolutionary history. FAST's sensitivity allowed for the measurement of the orbit's shape with unprecedented accuracy.
The discovery was reported in recent observations, though specific dates and the exact orbital parameters were not detailed in the available source. FAST is the world's largest single-dish radio telescope, which has been operating since 2020 and has contributed to several pulsar discoveries.
This finding deepens understanding of binary star systems and the processes that shape them. The near-circular orbit indicates little tidal distortion or external perturbation over the pulsar's lifetime, supporting models of stable mass transfer between stars.
Counterargument: The source notes only the orbit's circularity; without additional spectroscopic or timing data, the system's age and formation mechanism remain theoretical. Confirming the evolutionary scenario will require further observations.
