Low-temperature gas opacity - AESOPUS: a versatile and quick computational tool
Paola Marigo, Bernhard Aringer
We introduce a new tool - AESOPUS: Accurate Equation of State and OPacity Utility Software - for computing the equation of state and the Rosseland mean (RM) opacities of matter in…
The puzzling dredge-up pattern in NGC 1978
Michael T. Lederer, Thomas Lebzelter, Sergio Cristallo +3
Low-mass stars are element factories that efficiently release their products in the final stages of their evolution by means of stellar winds. Since they are large in number, they…
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…
