Physical properties of outflows: Comparing CO and H2O based parameters in Class 0 sources
P. Bjerkeli, R. Liseau, B. Nisini +4
Context. The observed physical properties of outflows from low-mass sources put constraints on possible ejection mechanisms. Historically, these quantities have been derived from C…
Preliminary results on SiO v=3 J=1-0 maser emission from AGB stars
J. -F. Desmurs, V. Bujarrabal, M. Lindqvist +3
We present the results of SiO maser observations at 43GHz toward two AGB stars using the VLBA. Our preliminary results on the relative positions of the different J=1-0 SiO masers (…
H2O line mapping at high spatial and spectral resolution - Herschel observations of the VLA1623 outflow
P. Bjerkeli, R. Liseau, B. Larsson +12
Apart from being an important coolant, H2O is known to be a tracer of high-velocity molecular gas. Recent models predict relatively high abundances behind interstellar shockwaves.…
Class I methanol masers in low-mass star formation regions
S. V. Kalenskii, V. I. Slysh, L. E. B. Johansson +4
Four Class I maser sources were detected at 44, 84, and 95 GHz toward chemically rich outflows in the regions of low-mass star formation NGC 1333I4A, NGC 1333I2A, HH25, and L1157.…
Herschel observations of the Herbig-Haro objects HH52-54
P. Bjerkeli, R. Liseau, B. Nisini +11
We are aiming at the observational estimation of the relative contribution to the cooling by CO and H2O, as this provides decisive information for the understanding of the oxygen c…
Detection of interstellar hydrogen peroxide
P. Bergman, B. Parise, R. Liseau +4
The molecular species hydrogen peroxide, HOOH, is likely to be a key ingredient in the oxygen and water chemistry in the interstellar medium. Our aim with this investigation is to…
