SS433
We propose an 80 ks observation of the Galactic microquasar SS 433 around an eclipse phase, consisting of a 50 ks exposure in eclipse and 30 ks out of eclipse, to investigate the jet structure by measuring the line widths of ionized metal lines emitted from different regions in the jets. High resolution X-ray spectroscopy of SS 433 with Resolve gives unique opportunity to understand the jet structure at supercritical accretion rates. The jet collimation of SS 433 can be resolved by comparing the velocity dispersions of Fe XXVI and Si XIV Ly alpha lines, and more direct evidence can be obtained from a comparison between the line structures in eclipse and and non-eclipse phases.
