Another interesting work led by Chinese Insight-HXMT collegues about my favorite source related to the spin-up episode we discused earlier. GX 301-2 provides a rare opportunity to study both disk and wind accretion in a same target. We reported on Insight-HXMT observations of the spin-up event of GX 301-2 happened in 2019 and compare with those of wind-fed state, which allowed to detect interesting pulse profile changes. Inspection of the Fermi/GBM data also confirmed Insight-HXMT results. We discuss possible differences between disk and wind accretion that may explain the observed different trend of pulse profiles.
