Pulsar discovered in an ultraluminous X-ray source

(Phys.org)—A team of European astronomers has discovered a new pulsar in a variable ultraluminous X-ray source (ULX) known as NGC 7793 P13. The newly found object is the third ultraluminous X-ray pulsar detected so far, and also the fastest-spinning one. The findings are detailed in a paper published Sept. 21 in the arXiv pre-print server.
