The weight-loss ability of a red giant star is determined at birth and is not affected by environment!
This was established by Karsten Brogaard of AU and a group of international collaborators and published in Astronomy & Astrophysics.
The paper is an ensemble study of giant stars combining asteroseismology of the Kepler satellite data with distances from the Gaia space mission and surface temperature and abundance measurements from the APOGEE spectroscopic survey.
More precisely, it was determined that the total mass-loss of red giant stars in the Milky Way's thick disc depends on their metallicity with the trend being opposite to what is found in the lower-metallicty globular cluster stars : higher-metallicty stars lose less mass than lower-metallicity stars.
At overlapping metallicities, the disk stars and the globular cluster stars show similar mass-loss. Thus, the mass-loss mechanism seems to be the same in the two environments, although the metallicity dependence reverses at even lower metallicities.
It is the hope that this new knowledge can lead to a physical understanding of the mass-loss phenomenon in red giant stars.
