Astronomers report the finding of a new candidate redback millisecond pulsar (MSP) binary associated with a gamma-ray source known as 4FGL J0940.3–7610. The newly found object is a short-period compact binary exhibiting X-ray emission that consists of a low-mass neutron star and a companion star with a mass most likely over 0.4 solar masses. The discovery is detailed in a paper published January 21 on the arXiv pre-print server.
