Outflows from Young Stars and the Interstellar Medium
Star Formationv. 2000
Star Formation v. 2000: The Bare Essentials
How the Recipe Works
Do Outflows Ever žCreateÓ Cloud Structures?If so, how does this effect future star formation & the žclump mass spectrumÓ?
Radio Spectral-line Observations of Molecular Clouds
žClumpÓ Mass Distribution
Keep in Mind...
Examples that might convince you that YSO Outflows Move More Gas than You Thought
žGiantÓ Herbig-Haro Flows:PV Ceph
MatchingEjectionAngles(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
