Resolving the shocked gas in HH54 with Herschel: CO line mapping at high spatial and spectral resolution
P. Bjerkeli, R. Liseau, C. Brinch +11
The HH54 shock is a Herbig-Haro object, located in the nearby Chamaeleon II cloud. Observed CO line profiles are due to a complex distribution in density, temperature, velocity, an…
Shockingly low water abundances in Herschel / PACS observations of low-mass protostars in Perseus
A. Karska, L. E. Kristensen, E. F. van Dishoeck +16
Protostars interact with their surroundings through jets and winds impacting on the envelope and creating shocks, but the nature of these shocks is still poorly understood. Our aim…
First spectrally-resolved H observations towards HH 54 / Low HO abundance in shocks
G. Santangelo, S. Antoniucci, B. Nisini +11
Context: Herschel observations suggest that the HO distribution in outflows from low-mass stars resembles the H emission. It is still unclear which of the different excitat…
Water in star-forming regions with Herschel (WISH) V. The physical conditions in low-mass protostellar outflows revealed by multi-transition water observations
J. C. Mottram, L. E. Kristensen, E. F. van Dishoeck +17
Context: Outflows are an important part of the star formation process as both the result of ongoing active accretion and one of the main sources of mechanical feedback on small sca…
Water distribution in shocked regions of the NGC1333-IRAS4A protostellar outflow
G. Santangelo, B. Nisini, C. Codella +11
We present the study of the H2O spatial distribution at two bright shocked regions along IRAS4A, one of the strongest H2O emitters among the Class 0 outflows. We obtained Herschel-…
