XRISM measured gas plunging toward pulsar GX 301−2 at 540,000 km/h as it crossed Wray 977’s stellar wind—and found evidence that its turbulent disk breaks apart before rebuilding in the opposite direction.

XRISM's iron-line spectrum directly measured plasma falling onto GX 301−2, while the disk-breakup and reversal sequence remains a model supported by spectra and Fermi timing.
