Spitzer Space Telescope spectra of post-AGB stars in the Large Magellanic Cloud ---polycyclic aromatic hydrocarbons at low metallicities
Mikako Matsuura, Jeronimo Bernard-Salas, T. Lloyd Evans +26
This paper reports variations of polycyclic aromatic hydrocarbons (PAHs) features that were found in Spitzer Space Telescope spectra of carbon-rich post-asymptotic giant branch (po…
Silicate features in Galactic and extragalactic post-AGB discs
C. Gielen, J. Bouwman, H. Van Winckel +7
Aims. In this paper we study the Spitzer and TIMMI2 infrared spectra of post-AGB disc sources, both in the Galaxy and the LMC. Using the observed infrared spectra we determine the…
The optically bright post-AGB population of the LMC
E. van Aarle, H. Van Winckel, T. Lloyd Evans +3
The detected variety in chemistry and circumstellar shell morphology of the limited sample of Galactic post-AGB stars is so large that there is no consensus yet on how the differen…
SPITZER-IRS spectral fitting of discs around binary post-AGB stars - Corrigendum
C. Gielen, H. Van Winckel, M. Min +15
Recently, we have discovered an error in our Monte-Carlo spectral fitting routine, more specifically where the errors on the fluxes were rescaled to get a reduced chi2 of 1. The re…
Chemical depletion in the Large Magellanic Cloud: RV Tauri stars and the photospheric feedback from their dusty discs
C. Gielen, H. Van Winckel, M. Reyniers +11
Aims: By studying the photospheric abundances of 4 RV Tauri stars in the LMC, we test whether the depletion pattern of refractory elements, seen in similar Galactic sources, is als…
SPITZER survey of dust grain processing in stable discs around binary post-AGB stars
C. Gielen, H. Van Winckel, M. Min +2
Aims: We investigate the mineralogy and dust processing in the circumbinary discs of binary post-AGB stars using high-resolution TIMMI2 and SPITZER infrared spectra. Methods: We pe…
