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…

Seismic diagnostics of solar-like oscillating stars

Yaguang Li, Minghao Du, Bohan Xie +5

High precision and long-lasting \emph{Kepler} data enabled us to estimate stellar properties with asteroseismology as an accurate tool. We performed asteroseismic analysis on six s…

Asteroseismic analysis of two alpha-enhanced stars KIC 7976303 and KIC 8694723

Z. S. Ge, S. L. Bi, T. D. Li +5

We intent to use stellar models with and without alpha-enhancement, as well as asteroseismic analysis, to study two alpha-enhanced stars, KIC 7976303 and KIC 8694723. For the alpha…

Asteroseismic analysis of the CoRoT target HD49933

Zhie Liu, Wuming Yang, Shaolan Bi +9

The frequency ratios and of HD 49933 exhibit an increase at high frequencies. This behavior also exists in the ratios of other stars, which is considered to result from the low sig…

The Contributions of Interactive Binary Stars to Double Main Sequence Turn-Offs and Dual Red Clump of Intermediate-Age Star Clusters

Wuming Yang, Xiangcun Meng, Shaolan Bi +3

Double or extended main-sequence turn-offs (DMSTOs) and dual red clump (RC) were observed in intermediate-age clusters, such as in NGC 1846 and 419. the DMSTOs are interpreted as t…
