Structure and Dynamics of the Bok Globule B335.
01 January 1987
The structural and dynamical properties of the Bok globule, B335, are determined from extensive millimetric spectral observations of CO and HCO+ isotopes and various other molecular species. These new, high sensitivity observations reveal that B335 is much more extended and complex than previous optical and molecular line observations have shown. We find that B335 consists of several components. It contains a condensed core with a mass of 11-14 M(o) coincident with the optically opaque core. Embedded in the core is a low mass star or protostar as evidenced by high velocity flows and far infrared photometry. The core is collapsing at a rate considerably smaller than that of free fall and rotating with a period of 1.7x10(7) years.
