Carbon stars in the X-shooter Spectral Library
A. Gonneau, A. Lançon, S. C. Trager +13
We provide a new collection of spectra of 35 carbon stars obtained with the ESO/VLT X-shooter instrument as part of the X-shooter Spectral Library project. The spectra extend from…
Is there a metallicity ceiling to form carbon stars? - A novel technique reveals a scarcity of C stars in the inner M31 disk
M. L. Boyer, L. Girardi, P. Marigo +10
We use medium-band near-infrared (NIR) Hubble Space Telescope WFC3 photometry with model NIR spectra of Asymptotic Giant Branch (AGB) stars to develop a new tool for efficiently di…
Long-period variables in NGC147 and NGC185
D. Lorenz, T. Lebzelter, W. Nowotny +4
Previous studies on the stellar content of the two nearby dwarf galaxies NGC147 and NGC185 reveal a rich population of late-type giants in both systems, including a large number of…
Abundance analysis for long period variables. Velocity effects studied with O-rich dynamic model atmospheres
T. Lebzelter, W. Nowotny, S. Höfner +3
(abbreviated) Measuring the surface abundances of AGB stars is an important tool for studying the effects of nucleosynthesis and mixing in the interior of low- to intermediate mass…
Synthetic photometry for carbon rich giants, I. Hydrostatic dust-free models
B. Aringer, L. Girardi, W. Nowotny +2
We study the spectroscopic and photometric properties of carbon stars. In the first paper of this series we focus on objects that can be described by hydrostatic models neglecting…
Interferometric properties of pulsating C-rich AGB stars I. Intensity profiles and uniform disc diameters of dynamic model atmospheres
C. Paladini, B. Aringer, J. Hron +3
We present the first theoretical study on center-to-limb variation (CLV) properties and relative radius interpretation for narrow and broad-band filters, on the basis of a set of d…
Modelling NIR molecular lines for Miras
W. Nowotny, S. Hoefner, T. Lebzelter +2
The atmospheric structure of Mira variables is considerably influenced by pulsation. Molecular absorption lines in the near-infrared (NIR), especially second overtone CO lines, sho…
