Observations of small-scale structure in AGB star winds: Precursors of neutral globules in PNE?

Research output: Contribution to journalConference article

Abstract

Millimeter-interferometric mapping of thermal emission from molecules which trace dense gas reveals much clumpy structure in the envelopes of two AGB stars. Observations were made with the Caltech OVRO mm-array. The signal-to-noise ratio of the data allowed use of self-calibration to achieve high dynamic range images (∼ 100:1) in individual spectral channel maps of 0.7 km s-1 width. The angular resolution is ∼ 2″.
