3D NLTE modelling of Y and Eu. Centre-to-limb variation and solar abundances
N. Storm, P. S. Barklem, S. A. Yakovleva +6
Context. Abundances of s- and r-process elements in Sun-like stars constrain nucleosynthesis in extreme astrophysical events, such as compact binary mergers and explosions of highl…
Theoretical Study of Inelastic Processes in Collisions of Y and Y with Hydrogen Atom
Yu Wang, Sofya Alexeeva, Feng Wang +6
Utilizing a simplified quantum model approach, the low-energy inelastic collision processes between yttrium atoms (ions) and hydrogen atoms have been studied. Rate coefficients cor…
Titanium abundances in late-type stars I. 1D non-local thermodynamic equilibrium modelling in benchmark dwarfs and giants
J. W. E. Mallinson, K. Lind, A. M. Amarsi +4
The titanium abundances of late-type stars are important tracers of Galactic formation history. However, abundances inferred from Ti I and Ti II lines can be in stark disagreement…
Non-LTE abundances of zinc in different spectral type stars and the Galactic [Zn/Fe] trend based on quantum-mechanical data on inelastic processes in zinc-hydrogen collisions
T. M. Sitnova, S. A. Yakovleva, A. K. Belyaev +1
We present a new model atom of Zn I-II based on the most up-to-date photoionisation cross-sections, electron-impact excitation rates, and rate coefficients for the Zn I + H I and Z…
Inelastic processes in strontium-hydrogen collisions and their impact on non-LTE calculations
Svetlana A. Yakovleva, Andrey K. Belyaev, Lyudmila I. Mashonkina
Inelastic processes rate coefficients for low-energy Sr + H, Sr + H, Sr + H and Sr + H collisions are calculated using multichannel quantum model approach. 3…
Geometric Upper Critical Dimensions of the Ising Model
Sheng Fang, Zongzheng Zhou, Youjin Deng
The upper critical dimension of the Ising model is known to be , above which critical behavior is regarded as trivial. We hereby argue from extensive simulations that, in th…
