APEX 1 mm line survey of the Orion Bar
S. Leurini, R. Rolffs, S. Thorwirth +8
Unbiased molecular line surveys are a powerful tool for analyzing the physical and chemical parameters of astronomical objects and are the only means for obtaining a complete view…
The distribution of ND2H in LDN1689N
Maryvonne Gerin, Dariuscz C. Lis, Sabine Philipp +3
Finding tracers of the innermost regions of prestellar cores is important for understanding their chemical and dynamical evolution before the onset of gravitational collapse. While…
Mid- and high-J CO observations towards UCHIIs
F. Wyrowski, S. Heyminck, R. Guesten +1
A study of 12 ultracompact HII regions was conducted to probe the physical conditions and kinematics in the inner envelopes of the molecular clumps harboring them. The APEX telesco…
Revealing the environs of the remarkable southern hot core G327.3-0.6
F. Wyrowski, K. M. Menten, P. Schilke +3
We present a submm study of the massive hot core G327.3-0.6 that constrains its physical parameters and environment. The APEX telescope was used to image CO and N2H+ emission, to o…
APEX mapping of H3O+ in the Sgr B2 region
F. F. S. van der Tak, ; A. Belloche, P. Schilke +5
The cosmic-ray ionization rate (zeta) of dense molecular clouds is a key parameter for their dynamics and chemistry. Variations of zeta are well established, but it is unclear if t…
Discovery of Interstellar CF+
D. A. Neufeld, P. Schilke, K. M. Menten +7
We discuss the first astronomical detection of the CF+ (fluoromethylidynium) ion, obtained by observations of the J=1-0 (102.6 GHz), J=2-1 (205.2 GHz) and J=3-2 (307.7 GHz) rotatio…
