Monitor variability of millimeter lines in IRC +10216
J. H. He, Dinh-V-Trung, T. I. Hasegawa
A single dish monitoring of millimeter maser lines SiS J=14-13 and HCN nu_2 = 1^f J=3-2 and several other rotational lines is reported for the archetypal carbon star IRC+10216. Rel…
Discovery of a distant molecular cloud in the extreme outer Galaxy with the Nobeyama 45-m telescope
Mitsuhiro Matsuo, Hiroyuki Nakanishi, Tetsuhiro Minamidani +10
We report the discovery of the molecular cloud whose kinematic distance is the largest in the Galaxy at the present moment, named G213.0420.003, at 213.042 and $b…
Discovery of Mira variable stars in the metal-poor Sextans dwarf spheroidal galaxy
T. Sakamoto, N. Matsunaga, T. Hasegawa +1
We report the discovery of two Mira variable stars (Miras) toward the Sextans dwarf spheroidal (dSph) galaxy. We performed optical long-term monitoring observations for two red sta…
Kinematics of Red Variables in the Solar Neighborhood I. Basic Data Obtained by an SiO Maser Survey
S. Deguchi, T. Sakamoto, T. Hasegawa
In order to study the streaming motions of miras in the Solar neighborhood, we newly surveyed 379 red variables in the SiO maser lines at 42.821 and 43.122 GHz with the Nobeyama 45…
Aperture Synthesis Observations of CO, HCN, and 89GHz Continuum Emission toward NGC 604 in M 33: Sequential Star Formation Induced by Supergiant Hii region
Rie Miura, Sachiko K. Okumura, Tomoka Tosaki +7
We present the results from new Nobeyama Millimeter Array observations of CO(1-0), HCN(1-0), and 89-GHz continuum emissions toward NGC 604, known as the supergiant H ii region in a…
An extended star cluster at the outer edge of the spiral galaxy M33
Rima Stonkute, Vladas Vansevicius, Nobuo Arimoto +6
We report a discovery of an extended globular-like star cluster, M33-EC1, at the outer edge of the spiral galaxy M33. The distance to the cluster is 890 kpc, and it lies at a 12.5…
