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…

Chemical differentiation in regions of high-mass star formation I. CS, dust and N2H^+ in southern sources

L. Pirogov, I. Zinchenko, P. Caselli +1

Aims. Our goals are to compare the CS, N2H+ and dust distributions in a representative sample of high-mass star forming dense cores and to determine the physical and chemical prope…

Low-mass star formation in Lynds 1333

M. Kun, S. Nikolic, L. E. B. Johansson +2

Medium-resolution optical spectroscopy of the candidate YSOs associated with the small, nearby molecular cloud Lynds~1333 revealed four previously unknown classical T Tauri stars,…

Mass-loss properties of S-stars on the AGB

S. Ramstedt, F. L. Schoeier, H. Olofsson +1

We have used a detailed non-LTE radiative transfer code to model new APEX CO(J=3-2) data, and existing CO radio line data, on a sample of 40 AGB S-stars. The derived mass-loss-rate…

IRAC and MIPS Observations of the Interacting Galaxies IC 2163 and NGC 2207: Clumpy Emission

Debra Meloy Elmegreen, Bruce G. Elmegreen, Michele Kaufman +4

IC 2163 and NGC 2207 are interacting galaxies that have been well studied at optical and radio wavelengths and simulated in numerical models to reproduce the observed kinematics an…

The distribution of SiO in the circumstellar envelope around IRC+10216

F. L. Schoeier, D. Fong, H. Olofsson +2

New interferometric observations of SiO J=5-4 circumstellar line emission around the carbon star IRC+10216, using the Submillimeter Array, are presented. Complemented by multi-tran…
