Outflows from Young Stars and the Interstellar Medium
Star Formation v. 2000
Star Formation v. 2000: The Bare Essentials
How the Recipe Works
PPT Slide
Do Outflows Ever ìCreateî Cloud Structures? If so, how does this effect future star formation & the ìclump mass spectrumî?
Radio Spectral-line Observations of Molecular Clouds
ìOutflowî Spectra
ìClumpî Mass Distribution
Keep in Mind...
Examples that might convince you that YSO Outflows Move More Gas than You Thought
ìGiantî Herbig-Haro Flows: PV Ceph
Matching Ejection Angles (assumes episodic ejections from precessing or wobbling stationery source)
Matching Ejection Distance (preferred by Reipurth)
A New Proposal: Episodic ejections from precessing or wobbling moving source
ìGiantî Herbig-Haro Flows
PV Ceph
ìAmbientî Gas in PV Ceph

3. Are Some Dark Clouds Created by Outflows?
