Sub-millimeter Observations of Giant Molecular Clouds in the Large Magellanic Cloud: Temperature and Density as Determined from J=3-2 and J=1-0 transitions of CO
T. Minamidani, N. Mizuno, Y. Mizuno +26
We have carried out sub-mm 12CO(J=3-2) observations of 6 giant molecular clouds (GMCs) in the Large Magellanic Cloud (LMC) with the ASTE 10m sub-mm telescope at a spatial resolutio…
A centimetre-wave excess over free-free emission in planetary nebulae
S. Casassus, L. -A. Nyman, C. Dickinson +1
We report a centimetre-wave (cm-wave, 5-31GHz) excess over free-free emission in PNe. Accurate 31 and 250GHz measurements show that the 31GHz flux densities in our sample are syste…

Detection of HCO+ Emission toward the Planetary Nebula K 3-35
D. Tafoya, Y. Gomez, G. Anglada +8
We report the detection, for the first time, of HCO+ (J=1-0) emission as well as marginal CO (J=1-0) emission toward the planetary nebula (PN) K3-35 as a result of a molecular surv…
First observations with CONDOR, a 1.5 THz heterodyne receiver
M. C. Wiedner, G. Wieching, F. Bielau +15
The THz atmospheric windows centered at roughly 1.3 and 1.5~THz, contain numerous spectral lines of astronomical importance, including three high-J CO lines, the N+ line at 205 mic…
Molecules in bipolar proto-planetary nebulae
Paul M. Woods, L. -A. Nyman, F. L. Schoeier +3
Two bipolar proto-planetary nebulae, IRAS16594-4656 and IRAS17150-3224, have been detected in various molecular lines, namely CO, ^{13}CO, HCN and CN, and remain undetected in seve…
