Carbon star wind models at solar and sub-solar metallicities: a comparative study. I. Mass loss and the properties of dust-driven winds
S. Bladh, K. Eriksson, P. Marigo +2
The atmospheres and winds of C-type AGB stars are modeled with the 1D spherically symmetric radiation-hydrodynamical code DARWIN. To explore the metallicity-dependence of mass loss…
Dust-driven winds of AGB stars: The critical interplay of atmospheric shocks and luminosity variations
S. Liljegren, S. Höfner, W. Nowotny +1
Winds of AGB stars are thought to be driven by a combination of pulsation-induced shock waves and radiation pressure on dust. In dynamic atmosphere and wind models, the stellar pul…
HE 0557-4840 - Ultra-Metal-Poor and Carbon-Rich
John E. Norris, N. Christlieb, A. J. Korn +5
We report the discovery and high-resolution, high S/N, spectroscopic analysis of the ultra-metal-poor red giant HE 0557-4840, which is the third most heavy-element deficient star c…
HE1327-2326, an unevolved star with [Fe/H]<-5.0. I. A Comprehensive Abundance Analysis
W. Aoki, A. Frebel, N. Christlieb +17
We present the elemental abundances of HE1327-2326, the most iron-deficient star known, determined from a comprehensive analysis of spectra obtained with the Subaru Telescope High…
