Aperture synthesis observations of HCN J=1-0 emission from Y canum venaticorum
We have made high resolution observations of HCN (1-0) emission from the carbon star Y Canum Venaticorum using the Nobeyama Millimeter Array. We find that the emission region is not well resolved by the synthe...

Molecular and low excitation emission in high mass post-main-sequence nebulae
We have undertaken map** and spectroscopy of a broad range of type I post-Main-Sequence nebulae in COJ=1→0,J=2→1, andJ=3→2, using the 12 m antenna at Kitt Peak, and the 45 m facility of the Nobeyama Radio Obser...

Molecular Clouds in the Central 100-pc of the Galactic Center
We have observed CS(J=1–0/2–1) lines in a 60’×30’(1×b) area of the Galactic center region. There are two large-scale features with elliptical shape in the position-velocity maps, which suggest shell-like struc...

Distribution of the H2O Masers in the Sagittarius B2 Core
The distribution of H2O masers in the Sgr B2 core was observed with a 2.5′×2.5′ wide field and with 540 km s-1 total velocity coverage by the Nobeyama Millimeter Array. Thirty-nine resolved maser spots were detec...
