The ALMA detection of CO rotational line emission in AGB stars in the Large Magellanic Cloud
M. A. T. Groenewegen, W. H. T. Vlemmings, P. Marigo +21
Context: Low- and intermediate-mass stars lose most of their stellar mass at the end of their lives on the asymptotic giant branch (AGB). Determining gas and dust mass-loss rates (…
SAGE-Var: An Infrared Survey of Variability in the Magellanic Clouds
D. Riebel, M. L. Boyer, S. Srinivasan +9
We present the first results from the SAGE-Var program, a follow on to the Spitzer legacy program Surveying the Agents of Galaxy Evolution (SAGE; Meixner, et al. 2006). We obtained…
The yellow hypergiant HR 5171 A: Resolving a massive interacting binary in the common envelope phase
O. Chesneau, A. Meilland, E. Chapellier +20
We initiated long-term optical interferometry monitoring of the diameters of unstable yellow hypergiants (YHG) with the goal of detecting both the long-term evolution of their radi…
The Spitzer Spectroscopic Survey of S-type Stars
K. Smolders, P. Neyskens, J. A. D. L. Blommaert +28
S-type AGB stars are thought to be in the transitional phase between M-type and C-type AGB stars. Because of their peculiar chemical composition, one may expect a strong influence…
The Cepheid distance to the Local Group Galaxy NGC 6822
M. W. Feast, P. A. Whitelock, J. W. Menzies +1
Recent estimates of the Cepheid distance modulus of NGC 6822 differ by 0.18 mag. To investigate this we present new multi-epoch JHKs photometry of classical Cepheids in the central…
Spitzer Space Telescope spectral observations of AGB stars in the Fornax dwarf spheroidal galaxy
M. Matsuura, A. A. Zijlstra, J. Bernard-Salas +10
We have observed five carbon-rich AGB stars in the Fornax dwarf spheroidal (dSph) galaxy, using the Infrared Spectrometer on board the Spitzer Space Telescope. The stars were selec…
Hubble Space Telescope Fine Guidance Sensor Parallaxes of Galactic Cepheid Variable Stars: Period-Luminosity Relations
G. Fritz Benedict, Barbara E. McArthur, Michael W. Feast +6
(abridged) We present new absolute trigonometric parallaxes and relative proper motions for nine Galactic Cepheid variable stars: l Car, zeta Gem, beta Dor, W Sgr, X Sgr, Y Sgr, FF…
