A spatially resolved study of photoelectric heating and [CII] cooling in the LMC
D. Rubin, S. Hony, S. C. Madden +20
(abridged) We study photoelectric heating throughout the Large Magellanic Cloud. We quantify the importance of the [CII] cooling line and the photoelectric heating process of vario…
Detection of `parent' molecules from the inner wind of AGB stars as tracers of non-equilibrium chemistry
L. Decin, I. Cherchneff, S. Hony +3
Asymptotic Giant Branch (AGB) stars are typified by strong dust-driven, molecular outflows. For long, it was believed that the molecular setup of the circumstellar envelope of AGB…
The variable mass loss of the AGB star WX Psc as traced by the CO J=1-0 through 7-6 lines and the dust emission
L. Decin, S. Hony, A. de Koter +3
Low and intermediate mass stars lose a significant fraction of their mass through a dust-driven wind during the Asymptotic Giant Branch (AGB) phase. Recent studies show that winds…
Continuum emission around AGB stars at 1.2 mm
S. Dehaes, M. A. T. Groenewegen, L. Decin +3
It is generally acknowledged that the mass loss of Asymptotic Giant Branch (AGB) stars undergoes variations on different time scales. We constructed models for the dust envelopes f…
Spitzer spectroscopy of carbon stars in the Small Magellanic Cloud
Eric Lagadec, Albert A. Zijlstra, G. C. Sloan +12
We present Spitzer Space telescope spectroscopic observations of 14 carbon-rich AGB stars in the Small Magellanic Cloud. SiC dust is seen in most of the carbon-rich stars but it is…
Probing the mass-loss history of AGB and red supergiant stars from CO rotational line profiles I. Theoretical model -- Mass-loss history unravelled in VY CMa
L. Decin, S. Hony, A. de Koter +3
Context: Mass loss plays a dominant role in the evolution of low mass stars while they are on the Asymptotic Giant Branch (AGB). The gas and dust ejected during this phase are a ma…
Spitzer observations of acetylene bands in carbon-rich AGB stars in the Large Magellanic Cloud
M. Matsuura, P. R. Wood, G. C. Sloan +13
We investigate the molecular bands in carbon-rich AGB stars in the Large Magellanic Cloud (LMC), using the InfraRed Spectrograph (IRS) on board the Spitzer Space Telescope (SST) ov…
A Spitzer mid-infrared spectral survey of mass-losing carbon stars in the Large Magellanic Cloud
Albert A. Zijlstra, Mikako Matsuura, Peter R. Wood +13
We present a Spitzer Space Telescope spectroscopic survey of mass-losing carbon stars (and one oxygen-rich star) in the Large Magellanic Cloud. The spectra cover the wavelength ran…
The profiles of the 3 to 12 m PAH features
B. van Diedenhoven, E. Peeters, C. Van Kerckhoven +4
We present spectra of the 3.3 m and 11.2 m PAH features of a large number of (extra-) galactic sources, obtained with ISO-SWS. Clear variations are present in the profiles of…
PAHs and crystalline silicates in the post-AGB star IRAS 16279-4757
M. Matsuura, A. A. Zijlstra, F. J. Molster +7
IRAS 16279-4757 belongs to a group of post-AGB stars showing both PAH bands and crystalline silicates. We present mid-infrared images, that resolve the object for the first time. T…
MgS in detached shells around carbon stars. Mining the mass-loss history
S. Hony, J. Bouwman
We investigate the dust composition of detached shells around carbon stars, with a focus to understand the origin of the cool magnesium-sulfide (MgS) material around warm carbon st…
The rich 6 to 9 um spectrum of interstellar PAHs
E. Peeters, S. Hony, C. Van Kerckhoven +4
Here, we present 6-9 um spectra of a sample of RNe, HII regions, YSOs, evolved stars and galaxies that show strong unidentified infrared bands, obtained with the ISO-SWS. The IR em…
The carrier of the "30" micron emission feature in evolved stars. A simple model using magnesium sulfide
S. Hony, L. B. F. M. Waters, A. G. G. M. Tielens
We present 2-45 micron spectra of a large sample of carbon-rich evolved stars in order to study the ``30'' micron feature. We find the ``30'' micron feature in sources in a wide ra…
The discovery of the "21" micron and "30" micron emission features in Planetary Nebulae with Wolf-Rayet central stars
S. Hony, L. B. F. M. Waters, A. G. G. M. Tielens
We report the discovery of the "21" micron and "30" micron features in the planetary nebulae around the hydrogen-deficient stars HD 826 and HD 158269. The carriers of these feature…
The CH out-of-plane bending modes of PAH molecules in astrophysical environments
S. Hony, C. Van Kerckhoven, E. Peeters +3
We present 10-15 micron spectra of a sample of H II regions, YSOs and evolved stars that show strong unidentified infrared emission features, obtained with the ISO/SWS spectrograph…
The infrared spectrum of the Be star gamma Cassiopeiae
S. Hony, L. B. F. M. Waters, P. A. Zaal +6
We present the 2.4-45 micrometer ISO-SWS spectrum of the Be star gamma Cas (B0.5 IVe). The spectrum is characterised by a thermal continuum which can be well fit by a power-law S_n…
