FAST detection of OH emission in the carbon-rich planetary nebula NGC 7027
Xu-Jia Ouyang, Yong Zhang, Chuan-Peng Zhang +8
We present the first detection of the ground-state OH emission line at 1612 MHz toward the prototypical carbon-rich planetary nebula (PN) NGC 7027, utilizing the newly installed ul…
Excited-State OH Masers in the Water Fountain Source IRAS 18460-0151
Xu-Jia Ouyang, Yong Zhang, Juan Li +3
Water fountain objects are generally defined as "evolved stars with low to intermediate initial mass accompanied by high-velocity molecular jets detectable in the 22.235 GHz HO…
FAST search for circumstellar atomic hydrogen. II. Is BD+303639 an interacting planetary nebula?
Xu-Jia Ouyang, Yong Zhang, Albert Zijlstra +3
The young, compact, very high surface brightness but low excitation planetary nebula (PN) BD+303639 is one of the very few PNe that have been reported to exhibit the 21cm HI emissi…
Molecules in the peculiar age-defying source IRAS 19312+1950
Jian-Jie Qiu, Yong Zhang, Jun-ichi Nakashima +5
Context. IRAS 19312+1950 is an isolated infrared source that exhibits a characteristic quasi-point-symmetric morphology in the near- and mid-infrared images and is also very bright…
The Astrometric Animation of Water Masers towards the Mira Variable BX Cam
Shuangjing Xu, Hiroshi Imai, Youngjoo Yun +20
We report VLBI monitoring observations of the 22 GHz water (HO) masers around the Mira variable BX Cam, which were carried out as a part of the EAVN Synthesis of Stellar Mase…
FAST search for circumstellar atomic hydrogen--I: the young planetary nebula IC 4997
Xu-Jia Ouyang, Yong Zhang, Albert Zijlstra +3
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Guizhou, China, we detect the 21cm neutral atomic hydrogen absorption in the young planetary nebula IC 499…
