Spectroscopic stellar surface gravities from metallic line profiles

Abstract:

Accurate surface gravities are needed for studies of stellar atmospheres and to determine stellar masses. It is suggested that measurements of gravities for late type stars are usually subject to great uncertainties, especially as the results are sensitive to the assumed effective temperature. A method is therefore proposed using the damping wings of metal lines to measure the gravity; and weak lines from the same lower level as ...
