The University

A new 4-m millimeter wave telescope has been constructed at the Department of Physics and Astrophysics, of Nagoya University, mainly for the purpose of making rapid surveys of interstellar molecular lines. The observing site is located on the Higashiyama Campus of the University at an altitude of 70-m above sea level in Nagoya. Observations with this telescope started in December 1983.

Physical And Chemical

Millimeter wave observations of molecular lines provide a useful tool to study the chemistry of bipolar outflows. In this contribution we discuss recent observational results which have permitted to assess the chemical alterations of the ambient medium produced by the presence of bipolar collimated winds driven by young protostars. Discussed first are the results from molecular line surveys which have allowed to identify several species whose abundances in the outflow lobes are considerably enhanced with respect to that of the ambient medium. These enhancements are useful diagnostics of physical and chemical processes in the outflow lobes, such as sputtering of grain cores and/or desorption of grain mantles. Then we discuss the characteristics of the line profiles and of the spatial distribution of the emission in specific enhanced species, which provide information about the mechanisms responsible for the enhancements. In particular we give emphasis to the results derived from observations of two highly enhanced species, SiO and CH3OH, which are observed to trace different components of the outflows.

High resolution spectra of the 4.64 micron 1–0 R2 line of CO toward infrared sources in the galactic center reveal absorption components identified with features in radio and millimeter wave spectra of molecular lines. They demonstrate that the +20 km/s cloud is situated in front of the Sgr A West and the +50 km/s cloud is behind it. The spectra of IRS 3 and IRS 7 have strong absorptions near +50 km/s, which may originate in the 2 pc radius circumnuclear ring; if so then the western side of the ring lies in front of the galactic center. A less likely interpretation is that these objects, which are only a few arc-seconds from IRS 16, are behind the +50 km/s cloud and, thus, well behind the galactic center.
