Neutron Stars
Astronomers have observed dramatic changes in the neutron star P13 over a decade, as it transitioned from a faint state to high luminosity. Located in the galaxy NGC 7793, about 10 million light-years away, P13's X-ray output and rotation rate shifted significantly. These observations provide new insights into supercritical accretion processes.

The X-Ray Imaging and Spectroscopy Mission (XRISM) has observed an unexpectedly slow and dense wind from the neutron star system GX13+1, challenging models of radiation-driven outflows. This discovery highlights differences between winds around neutron stars and supermassive black holes. The findings could refine understanding of cosmic feedback processes.
