Proposal Abstract

SS433 is one of VSOP's most promising and challenging targets because of the radio-bright jet structure. A series of observations with intervals of <1 day will reveal evolution of jet blobs within 1 day, or 10 AU\@. The central engine and each blob will be resolved, and parameters of the jet such as mass, density, electron energy, magnetic field will be constrained. The unknown brightening mechanism of blobs at 4\times10^{15} cm from the jet engine will be explored. Decreasing-optical-depth mechanisms would be accompanied by expansion of blobs, while particle-injection scenarios would not necessarily. Distance, velocity, and inclination will be determined precisely by a method applicable only to this source. This observation would provide us a comprehensive understanding of the hierarchy of the jet structure, and of astrophysical jet phenomena ranging from binaries like GRS 1915+105 to AGN\@.

The full Cover Sheets (compressed post-script, typically 50kbytes) can be retrieved. Note that many proposals were reduced in extent by the Scientific Review Committee (e.g. by reducing the number of experiments), however the Cover Sheets contain the full proposal as submitted. Also note that AO2 proposals were submitted in May 1998, and information such as affiliations and contact details has changed for some proposers since that time. The Cover Sheets (and the details on this page, which were derived from the Cover Sheets) may therefore have changed.
