Chemical abundances and doppler imaging of the Ap Si/He-wk star HD 100357
Athul Dileep, Santosh Joshi, Sofya Alexeeva +11
We present the results of time-resolved photometry, abundance analysis and Doppler imaging of an Ap star, HD 100357. The {\it TESS} photometry revealed rotational modulation with a…
NLTE abundances of Eu for a sample of metal-poor stars in the Galactic Halo and Metal-poor Disk with 1D and <3D> models
Yanjun Guo, Nicholas Storm, Maria Bergemann +6
Accurate measurements of europium abundances in cool stars are essential for an enhanced understanding of the r-process mechanisms. We measure the abundance of Eu in solar spectra…
The Kinematic and Chemical Properties of the Close-in Planet Host Star 8 UMi
Huiling Chen, Yang Huang, Wei Zhu +11
A recent study by Hon et al. reported that a close-in planet around the red clump star, 8 UMi, should have been engulfed during the expansion phase of its parent star's evolution.…
A small scale structure model of jet based on the observation of microvariability
Jingran Xu, Shaoming Hu, Xu Chen +2
We developed a multi-region radiation model for the evolution of flux and spectral index with time. In this model, each perturbation component in the jet produces an independent fl…
NLTE analysis for Y I and Y II in atmospheres of F-G-K stars
Sofya Alexeeva, Yu Wang, Gang Zhao +5
The non-local thermodynamical equilibrium (NLTE) line formation of Y I and Y II is considered in 1D LTE model atmospheres of F-G-K-type stars. The model atom was constructed with t…
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…
