A Plasmoid Model for Mass Loss from Stars on the Upper Red Giant Branch: The Mass-loss Rate is Controlled by the Number of Density Scale Heights in the Convection Zone
Recent asteroseismic determinations of Δ M , the integrated mass loss on the red giant branch (RGB), for fields stars show a trend of Δ M decreasing as metallicity increases . This trend among field stars is inconsistent with many existing models of RGB mass loss. The present Letter is motivated by...
