The density structure of the L1157 molecular outflow
A. I. Gómez-Ruiz, C. Codella, B. Lefloch +6
We present a multiline CS survey towards the brightest bow-shock B1 in the prototypical chemically active protostellar outflow L1157. We made use of (sub-)mm data obtained in the f…
Empirical determination of Einstein A-coefficient ratios of bright [Fe II] lines
T. Giannini, S. Antoniucci, B. Nisini +6
The Einstein spontaneous rates (A-coefficients) of Fe^+ lines have been computed by several authors, with results that differ from each other up to 40%. Consequently, models for li…
POISSON project - III - Investigating the evolution of the mass accretion rate
S. Antoniucci, R. Garcia Lopez, B. Nisini +3
As part of the POISSON project (Protostellar Optical-Infrared Spectral Survey on NTT), we present the results of the analysis of low-resolution NIR spectra 0.9-2.4 um) of two sampl…
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…
