ALMA Observations of CO Isotopologues Towards Six Obscured post-AGB Stars
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.

Isotopic Enrichment Of Planetary Systems From Asymptotic Giant Branch Star
Short-lived radioisotopes, in particular 26-Al and 60-Fe, are thought to contribute to the internal heating of the Earth, but are significantly more abundant in the Solar System compared to the […]

Twinkling Stars Fuel Interstellar Dust
Of the many different kinds of stars, asymptotic giant branch (AGB) stars, usually slightly larger and older than our own sun, are known producers of interstellar dust.
