The unique capabilities of HST for stellar physics: Probing Atmospheric Structure, Chromospheres, and Mass Loss of Evolved Stars
Maryam Saberi, Graham Harper, Jacco Th. van Loon +10
Evolved stars are among the primary sources of chemical enrichment and dust production in galaxies. During the giant phases, stars return a substantial fraction of their mass to th…

A surprisingly large asymmetric ejection from Mira A
T. Khouri, W. H. T. Vlemmings, D. A. Raudales Oseguera +6
Stars with masses between roughly 1 and 8~ end their lives on the asymptotic giant branch (AGB), when intense mass loss takes place. The outflows are generally accepted to…

ALMA observations of CO isotopologues towards six obscured post-AGB stars
T. Khouri, D. Tafoya, W. H. T. Vlemmings +13
Low- and intermediate-mass stars evolve through the asymptotic giant branch (AGB), when an efficient mass-loss process removes a significant fraction of their initial mass. A subst…
