Reconstructing Intrinsic Stellar Noise with Stellar Atmospheric Parameters and Chromospheric Activity
Jinghua Zhang, Maosheng Xiang, Jie Yu +9
Accurately characterizing intrinsic stellar photometric noise induced by stellar astrophysics, such as stellar activity, granulation, and oscillations, is of crucial importance for…
Relations of rotation and chromospheric activity to stellar age for FGK dwarfs from Kepler and LAMOST
Lifei Ye, Shaolan Bi, Jinghua Zhang +9
The empirical relations between rotation period, chromospheric activity, and age can be used to estimate stellar age. To calibrate these relations, we present a catalog, including…
Lithium Evolution of Giant Stars Observed by LAMOST and Kepler
Jinghua Zhang, Jian-Rong Shi, Hong-Liang Yan +8
Mapping lithium evolution for evolved stars will provide restrictions and constraints on the fundamental stellar interior physical processes, which further shed light on our unders…
Variations of helioseismic parameters due to magnetic field generated by a flux transport model
Shaolan Bi, Tanda Li, Kang Liu +5
The change of sound speed has been found at the base of the convection during the solar cycles, which can be used to constrain the solar internal magnetic field. We aim to check wh…
Solar-type Stars Observed by LAMOST and Kepler
Jinghua Zhang, Alexander I. Shapiro, Shaolan Bi +8
Obtaining measurements of chromospheric and photometric activity of stars with near-solar fundamental parameters and rotation periods is important for a better understanding of sol…
Magnetic Activity of F-, G-, and K-type Stars in the LAMOST-Kepler Field
Jinghua Zhang, Shaolan Bi, Yaguang Li +10
Monitoring chromospheric and photospheric indexes of magnetic activity can provide valuable information, especially the interaction between different parts of the atmosphere and th…
