| Research Abstract |
We have carried out astrometic observations of H_2O maser sources associated with nearby molecular clouds with VERA. The aim of this project is to measure the accurate distances to molecular clouds within 1 kpc (3260 ly) from the Sun, and to reveal their 3 dimensional structures. It is also useful to refine physics and dynamics in star-formation processes. Thanks to accurate astrometry capability of VERA, we have succeeded in measuring trigonometric annual parallaxes of molecular clouds in the Cepheus (2490 ly) and Perseus (750 ly) regions.
