Outer rotation curve of the Galaxy with VERA. III. Astrometry of IRAS 07427−2400 and test of the density-wave theory
Abstract We report the trigonometric parallax of IRAS 07427−2400 with VERA to be 0.185 ± 0.027 mas, corresponding to a distance of 5.41$^{+0.92}_{-0.69}\:$kpc. The result is consistent with the previous result of 5.32$^{+0.49}_{-0.42}\:$kpc obtained by Choi et al. (2014, ApJ, 790, 99) within error. To remove the effect of internal …
