Proposal Abstract
The sizes of OH maser spots are sometimes found to be about 10 times smaller
than the expected in the model of interstellar scattering. To study the nature of
OH masers and scattering cloud we propose VSOP observations to image
interstellar OH masers in W75N, NGC7538, and Orion-KL at 1665 MHz and 1710 MHz.
The maps of the maser regions and images of individual maser spots will be
produced with an angular resolution of 1 milliarcsec which is several times higher
than the angular resolution available on the ground.
Since observations with ground-only
observations so far have only partially resolved OH maser spots, VSOP high
angular resolution may provide the crucial opportunity to achieve our goal.
The full Cover Sheets
(compressed post-script, typically 50kbytes) can
be retrieved. Note that some 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 AO4 proposals were submitted in October 2000,
and information such as affiliations and contact details has
changed for some proposers since that time.
