Absolute Magnitudes of Seismic Red Clumps in the Kepler Field and SAGA: the age dependency of the distance scale
Y. Q. Chen, L. Casagrande, G. Zhao +4
Red clump stars are fundamental distance indicators in astrophysics, although theoretical stellar models predict a dependence of absolute magnitudes with ages. This effect is parti…
Ages of 70 dwarfs of three populations in the solar neighborhood: considering O and C abundances in stellar models
Z. S. Ge, S. L. Bi, Y. Q. Chen +5
Oxygen and carbon are important elements in stellar populations. Their behavior refers to the formation history of the stellar populations. C and O abundances would also obviously…
Systematic non-LTE study of the [Fe/H] F and G dwarfs in the solar neighbourhood. II. Abundance patterns from Li to Eu
G. Zhao, L. Mashonkina, H. L. Yan +14
For the first time, we present an extensive study of stars with individual non-local thermodynamic equilibrium (NLTE) abundances for 17 chemical elements from Li to Eu in a sample…
Fundamental stellar parameters and age-metallicity relation of Kepler red giants in comparison with theoretical evolutionary tracks
Y. Takeda, A. Tajitsu, B. Sato +3
Spectroscopic parameters (effective temperature, metallicity, etc) were determined for a large sample of ~100 red giants in the Kepler field, for which mass, radius, and evolutiona…
