Scientific paper

Hybrid-chromosphere stars are G-K bright giants that show weak high-temperature emission lines and blue-shifted absorption in low-temperature lines indicating mass loss. We will determine the temperature distribution and densities in the outer atmosphere, and measure the outflow velocity and mass loss rate in a representative hybrid star, Alpha TrA. We will determine whether the hot plasma participates in the outflow or whether the wind consists entirely of cool gas. Atmospheric models will be derived for both the hot and cool gas using an emission measure analysis and density-sensitive line ratios. This work will settle the question of whether the hybrid nature of these stars is due to two distinct components in the stellar atmosphere (perhaps one with strong, closed magnetic fields and the other with weak, open fields) or whether a more complex geometry is needed to explain the data.
