SEPIA - a new single pixel receiver at the APEX Telescope
V. Belitsky, I. Lapkin, M. Fredrixon +31
Context: We describe the new SEPIA (Swedish-ESO PI Instrument for APEX) receiver, which was designed and built by the Group for Advanced Receiver Development (GARD), at Onsala Spac…
On the accretion process in a high-mass star forming region - A multitransitional THz Herschel-HIFI study of ammonia toward G34.26+0.15
M. Hajigholi, C. M. Persson, E. S. Wirström +8
[Abridged] Our aim is to explore the gas dynamics and the accretion process in the early phase of high-mass star formation. The inward motion of molecular gas in the massive star f…
SiO masers from AGB stars in the vibrationally excited v=1,v=2, and v=3 states
J. -F. Desmurs, V. Bujarrabal, M. Lindqvist +3
The v=1 and v=2 J=1-0 (43 GHz), and v=1 J=2-1 (86 GHz) SiO masers are intense in AGB stars and have been mapped using VLBI showing ring-like distributions. Those of the v=1, v=2 J=…
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.…
