KSw 71 is a rapidly-spinning star in the constellation of Lyra.
It is thought to have formed after two stars in a close binary system merged; its rotation has deformed it into an oblate spheroid shape.
KSw 71 was discovered, alongside other pumpkin-shaped stars by NASA's Kepler and Swift missions and produces X-rays at more than 100 times the peak levels ever seen from the Sun.
[4] 18 "pumpkin stars" have been discovered,[5] including this one.
