New energy from turbulent convection on mass loss in the RGB and EAGB stars

Based on the turbulent convection model, we propose new energy named turbulent thermal energy to explain the observed mass loss, and correspondingly propose a modified criterion on mass loss. We obtain the mass-loss rates and make a test of the proposal for the RGB and EAGB stars. The results coincide with the observational data, and also agree with the results of some other semi-empirical formulae based on the fundamental stellar parameters.

Automated summary

Based on the turbulent convection model, this study proposes a new energy called turbulent thermal energy to explain the observed mass loss, and introduces a modified criterion on mass loss. The obtained mass-loss rates are tested for RGB and EAGB stars, and the results are consistent with observational data and other semi-empirical formulae based on fundamental stellar parameters.
