An investigation of the formation and line properties of MgH in 3D hydrodynamical model stellar atmospheres
Anders O. Thygesen, Evan N. Kirby, Andrew J. Gallagher +4
Studies of the isotopic composition of magnesium in cool stars have so far relied upon the use of one-dimensional (1D) model atmospheres. Since the isotopic ratios derived are base…
An in-depth spectroscopic examination of molecular bands from 3D hydrodynamical model atmospheres. II. Carbon-enhanced metal-poor 3D model atmospheres
A. J. Gallagher, E. Caffau, P. Bonifacio +4
Context. Tighter constraints on metal-poor stars we observe are needed to better understand the chemical processes of the early Universe. Computing a stellar spectrum in 3D allows…
A three-dimensional hydrodynamical line profile analysis of iron lines and barium isotopes in HD140283
A. J. Gallagher, H. -G. Ludwig, S. G. Ryan +1
Heavy-elements, i.e. those beyond the iron peak, mostly form via two neutron capture processes: the s- and r-process. Metal-poor stars should contain fewer isotopes that form via t…
