Superdense neutron star caught feeding on a blue hypergiant's stellar wind
Filed by Dr. Kai Vega
Using data from the Japan–led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star's outflow, called a stellar wind, being captured by its compact companion and providing the power source for strong X-ray flares. The research is part of NASA's exploration of the extreme universe to better understand how the cosmos works.
