摘要

The luminous high-redshift (z = 2.17) quasar S5 0836 + 7 10 was observed in 1997 October with the VSOP at 1.6 GHz and 5 GHz. We report here a previously unpublished image made from the data at 1.6 GHz, and compare the structure of a relativistic jet in this quasar at two frequencies. We present a spectral index image tracing the spectral properties of the jet LIP to similar to 40 milliarcsec distance from the nucleus. The curved jet ridge line observed in the images and the spectral index distribution can be described by a Kelvin-Helmholtz instability developing in a relativistic outflow with a Mach number of similar to 6. In this description, the overall ridge line of the jet is formed by the helical surface mode of the Kelvin-Helmholtz instability, while areas of flatter spectral index embedded into the flow correspond to pressure enhancements produced by the elliptical surface mode of the instability. An alternative explanation involving a sequence of slowly dissipating shocks cannot be ruled out at this point.
