Interferometric view into RT Pav's long secondary period. binary vs oscillatory convective modes
B. Courtney-Barrer, X. Haubois, P. Wood +6
Long secondary periods (LSPs) occur in about one-third of evolved stars, yet their origin remains unclear. The leading explanations are oscillatory convective modes and a binary co…
A newly discovered stellar type: dusty post-red giant branch stars in the Magellanic Clouds
D. Kamath, P. R. Wood, H. Van Winckel +1
Context: We present a newly discovered class of low-luminosity, dusty, evolved objects in the Magellanic Clouds. These objects have dust excesses, stellar parameters, and spectral…
Chemical abundance study of two strongly s-process enriched post-AGB stars in the LMC: J051213.81-693537.1 and J051848.86-700246.9
K. De Smedt, H. Van Winckel, D. Kamath +1
Context: This paper is part of a larger project in which we study the chemical abundances of extra-galactic post-AGB stars with the ultimate goal of improving our knowledge of the…
Optically visible post-AGB/RGB stars and young stellar objects in the Small Magellanic Cloud: candidate selection, spectral energy distributions and spectroscopic examination
D. Kamath, P. R. Wood, H. Van Winckel
We have carried out a search for optically visible post-AGB candidates in the Small Magellanic Cloud (SMC). We used mid-IR observations from the Spitzer Space Telescope to select o…
The lead discrepancy in intrinsically s-process enriched post-AGB stars in the Magellanic Clouds
K. De smedt, H. Van Winckel, D. Kamath +4
Context: Our understanding of the s-process nucleosynthesis in asymptotic giant branch (AGB) stars is incomplete. AGB models predict, for example, large overabundances of lead (Pb)…
Evolution and Nucleosynthesis of AGB stars in Three Magellanic Cloud Clusters
D. Kamath, A. I. Karakas, P. R. Wood
We present stellar evolutionary sequences for asymptotic giant branch (AGB) stars in the Magellanic Cloud clusters NGC 1978, NGC 1846 and NGC 419. The new stellar models for the th…
