Astronomers from Wuhan University in China have employed the Insight-HXMT satellite to observe a giant outburst that occurred in the X-ray binary RX J0440.9+4431 about three years ago. Results of the observations, presented July 24 on the pre-print server arXiv, provide a wealth of data regarding the properties and behavior of this system.
