Spectroscopic parameters for silacyclopropynylidene, SiC, from extensive astronomical observations toward CW Leo (IRC +10216) with the Herschel satellite

H. S. P. Müller, J. Cernicharo, M. Agúndez +5

A molecular line survey has been carried out toward the carbon-rich asymptotic giant branch star CW Leo employing the HIFI instrument on board of the Herschel satellite. Numerous f…

A far-infrared survey of bow shocks and detached shells around AGB stars and red supergiants

N. L. J. Cox, F. Kerschbaum, A. -J. van Marle +16

Far-infrared Herschel/PACS images at 70 and 160 micron of a sample of 78 Galactic evolved stars are used to study the (dust) emission structures, originating from stellar wind-ISM…

The effect of intermediate mass close binaries on the chemical evolution of Globular Clusters

D. Vanbeveren, N. Mennekens, J. P. De Greve

Context. The chemical processes during the Asymptotic Giant Branch (AGB) evolution of intermediate mass single stars predict most of the observations of the different populations i…

HIFI detection of HF in the carbon star envelope IRC +10216

M. Agundez, J. Cernicharo, L. B. F. M. Waters +5

We report the detection of emission in the J=1-0 rotational transition of hydrogen fluoride (HF), together with observations of the J=1-0 to J=3-2 rotational lines of H35Cl and H37…

Diffuse interstellar bands in Upper Scorpius: Probing variations in the DIB spectrum due to changing environmental conditions

D. A. I. Vos, N. L. J. Cox, L. Kaper +2

We study the effects of local environmental conditions affecting the diffuse interstellar band (DIB) carriers within the Upper Scorpius subgroup of the Sco OB2 association. We obta…

On the polarisation of the Red Rectangle optical emission bands

N. L. J. Cox, B. H. Foing, J. Cami +1

The origin of the narrow optical emission bands seen toward the Red Rectangle is not yet understood. In this paper we investigate further the proposal that these are due to lumines…

Linear/circular spectropolarimetry of diffuse interstellar bands

N. L. J. Cox, P. Ehrenfreund, B. H. Foing +3

Context. The identification of the carriers of diffuse interstellar bands (DIBs) remains one of the long-standing mysteries in astronomy. The detection of a polarisation signal in…

Current assessment of the Red Rectangle band problem

R. J. Glinski, P. D. Michaels, C. M. Anderson +5

In this paper we discuss our insights into several key problems in the identification of the Red Rectangle Bands (RRBs). We have combined three independent sets of observations in…

Ices in the Quiescent IC 5146 Dense Cloud

J. E. Chiar, Y. J. Pendleton, L. J. Allamandola +14

This paper presents spectra in the 2 to 20 micron range of quiescent cloud material located in the IC 5146 cloud complex. The spectra were obtained with NASA's Infrared Telescope F…

Ice and Dust in the Quiescent Medium of Isolated Dense Cores

A. C. A. Boogert, T. L. Huard, A. M. Cook +6

The relation between ices in the envelopes and disks surrounding YSOs and those in the quiescent interstellar medium is investigated. For a sample of 31 stars behind isolated dense…

Chemically tagging the Hyades stream: Does it partly originate from the Hyades cluster?

L. Pompéia, T. Masseron, B. Famaey +19

The Hyades stream has long been thought to be a dispersed vestige of the Hyades cluster. However, recent analyses of the parallax distribution, of the mass function, and of the act…
