Astrometry of Galactic Star-Forming Region ON2N with VERA: Estimation of the Galactic Constants
Kazuma Ando,Takumi Nagayama,Toshihiro Omodaka,Toshihiro Handa,Hiroshi Imai,Akiharu Nakagawa,Hiroyuki Nakanishi,Mareki Honma,Hideyuki Kobayashi,Takeshi Miyaji +9 more
TL;DR: In this paper, the authors performed the astrometry of H2O masers in the Galactic star-forming region Onsala 2 North (ON 2 N) with the VLBI Exploration of Radio Astrometry (VERA), obtaining a trigonometric parallax of 0.261 ˙ 0.009 mas, corresponding to a heliocentric distance of 3.13 kpc.
