Scientific paper

SS 433 is possibly the most powerful galactic jet source and the key source for our understanding of super-Eddington accretion. With Chandra our group has discovered extended thermal X-ray jets indicating reheating of ions downstream in the jet. In simultaneous Chandra+VLA observations, plus archival Chandra images, we have discovered that these arcsec-scale jets undergo structural variability. Most dramatically, three archival images reveal significant variability on timescales <2 days. We can explain this rapid variability in terms of a relativistic shock propagating along the jet, and relate it to the jets (re-)brightening observed in radio in SS433, Sco X-1 & Cir X-1. To study this phenomenon we request 4x15ks simultaneous Chandra HRC+VLA observations of SS433, one every 2-to-6 days.
