Fe I/Fe II ionization equilibrium in cool stars: NLTE versus LTE
Lyudmila Mashonkina, Thomas Gehren, Jianrong Shi +2
Non-local thermodynamic equilibrium (NLTE) line formation for neutral and singly-ionized iron is considered through a range of stellar parameters characteristic of cool stars. A co…
Statistical equilibrium of silicon in the atmospheres of metal-poor stars
J. R. Shi, T. Gehren, L. Mashonkina +1
Aims. The statistical equilibrium of neutral and ionized silicon in the atmospheres of metal-poor stars is discussed. Non-local thermodynamic equilibrium effects are investigated a…
Model atmospheres of chemically peculiar stars: Self-consistent empirical stratified model of HD24712
D. Shulyak, T. Ryabchikova, L. Mashonkina +1
High-resolution spectra of some chemically peculiar stars clearly demonstrate the presence of strong abundance gradients in their atmospheres. However, these inhomogeneities are us…
Nucleosynthesis Modes in the High-Entropy-Wind of Type II Supernovae: Comparison of Calculations with Halo-Star Observations
K. Farouqi, K. -L. Kratz, L. I. Mashonkina +4
While the high-entropy wind (HEW) of Type II supernovae remains one of the more promising sites for the rapid neutron-capture (r-) process, hydrodynamic simulations have yet to rep…
