Variations of the mixing character of dipolar mixed modes in red giant stars
C. Jiang, M. Cunha, J. Christensen-Dalsgaard +1
Thanks to the high quality data of space missions, the detection of mixed modes has become possible in numerous stars. In this work, we investigate how the mixing character of dipo…
Numerical integral of resistance coefficients in diffusion
Q. S. Zhang
The resistance coefficients in screen Coulomb potential of stellar plasma are evaluated in high accuracy. I have analyzed the possible singularities in the integral of scattering a…
A simple scheme to implement a nonlocal turbulent convection model for the convective overshoot mixing
Q. S. Zhang
The classical 'ballistic' overshoot models show some contradictions and are not consistence with numerical simulations and asteroseismic studies. Asteroseismic studies imply that o…
The solar abundance problem: the effect of the turbulent kinetic flux on the solar envelope model
Q. S. Zhang
Recent 3D-simulations have shown that the turbulent kinetic flux (TKF) is significant. We discuss the effects of TKF on the size of convection zone and find that the TKF may help t…
Convective overshoot mixing in stellar interior models
Q. S. Zhang
The convective overshoot mixing plays an important role in stellar structure and evolution. However, the overshoot mixing is a long standing problem. The uncertainty of the oversho…
Testing the core overshooting mixing described by the turbulent convection model on the eclipsing binary star HY Vir
Q. S. Zhang
Helioseismic investigation has suggested to apply the turbulent convection models (TCMs) to the convective overshooting. Using the turbulent velocity in the overshooting region det…
The diffusive overshooting approach on Li abundance in clusters
Q. S. Zhang
The helioseimic investigation shows that the convective overshooting can penetrate to the location where the temperature is which is the typical tempera…
Turbulent convection model in the overshooting region: II. Theoretical analysis
Q. S. Zhang, Y. Li
Turbulent convection models are thought to be good tools to deal with the convective overshooting in the stellar interior. However, they are too complex to be applied in calculatio…
