Proposal Abstract

The Orion-KL region is one of the well-studied star forming region. It has all 3 major maser emisson, H_2O, OH and SiO. So this is important source to know about the outflow in this area, the emitting mechanisum of those maser lines, and the structure and the environment of IRc2 (source I), young stellar object. It was believed that the OH emission from Orion is too extend to observe with space-baseline. We found that it is marginally possible to observe with VSOP, from the analysis of pre-launch operation test observation in 1996. Therefore, we propose a observation to confirm the posibility of VSOP obseration, before submitting more complicate observations, such as polarization, multi-epoch observation.


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 AO3 proposals were submitted in October 1999, 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.
