Annual Parallax of the K-Type Star System IRAS 22480+6002 Measured with VERA
Abstract We present astrometric VLBI observations of H$_2$ O masers associated with IRAS 22480$+$ 6002 ($=$ IRC$+$ 60370, hereafter I22480) with the VLBI Exploration of Radio Astrometry (VERA). The stellar type of I22480 looks unusual in stellar maser sources, and has been debated since the 1970's. We successfully determined that …
