Maser Observations of Westerlund 1 and Comprehensive Considerations on Maser Properties of Red Supergiants Associated with Massive Clusters
Thomas K. T. Fok, Jun-ichi Nakashima, Bosco H. K. Yung +2
We report the results of Australia Telescope Compact Array (ATCA) observations of the Westerlund~1 (Wd1) region in the SiO v=1, J=1-0 and H2O 6(16)-5(23) maser lines, and we also r…
Discovery of a halo around the Helix Nebula NGC 7293 in the WISE all-sky survey
Yong Zhang, Chih-Hao Hsia, Sun Kwok
We report the discovery of an extended halo (40' in diameter) around the planetary nebula NGC7293 (the Helix Nebula) observed in 12micron band from the Wide-field Infrared Survey E…
[Fe III] emission lines in the planetary nebula NGC 2392
Y. Zhang, X. Fang, W. Chau +4
NGC 2392 is a young double-shell planetary nebula (PN). Its intrinsic structure and shaping mechanism are still not fully understood. In this paper we present new spectroscopic obs…
Extremely Strong ^{13}CO J=3-2 Line in the "Water Fountain" IRAS 16342-3814: Evidence for the Hot-Bottom Burning
Hiroshi Imai, Sze-Ning Chong, Jin-Hua He +5
We observed four "water fountain" sources in the CO J=3-2 line emission with the Atacama Submillimeter Telescope Experiment (ASTE) 10 m telescope in 2010-2011. The water fountain s…
The discovery based on GLIMPSE data of a protostar driving a bipolar outflow
J. H. Yuan, J. Z. Li, Y. F. Huang +2
We report the discovery based on GLIMPSE data of a proto-stellar system driving a bipolar outflow . The bipolar outflow closely resembles the shape of an hourglass in the infrared.…
