Spectropolarimetry Emission from SS433

In the last few years, spectropolarimetry has become an important tool in the study of AGN. Their geometry is obtained by comparing synthetic Stokes spectra with the observed spectropolarimetry. Similar techniques can be applied to the study of the scattering regions in the jets and disk of X-ray binary systems. We introduce a new code DESPEJO (Dynamical Evolution of Spectropolarimetry Emission of Jet Objects) that has been developed to analyze line intensity and polarization components in the emission from scattering regions on microquasars. In particular, the heating mechanisms and ejection of the gas in the jets of SS433 remain a mystery. Previous work on its polarized emission tried in vain to answer questions about the physical origin of its jets. Because SS433 has unique geometrical and dynamical configurations the study of synthetic polarimetric spectra and their evolution will give an important insight into the jet mechanism. We present our initial results with DESPEJO using the first spectropolarimetry data of this target. This method will give clues on the formation, acceleration, collimation and state of the gas bullets in its jets as well as on other properties of the system concerning the nature of the donor star and disk geometry.
