Backflow in Post-Asymptotic Giant Branch Stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We derive the conditions for a backflow toward the central star(s) of circumstellar material to occur during the post-asymptotic giant branch (AGB) phase. The backflowing material may be accreted by the post-AGB star and/or its companion, if such exists.

Isotopic Enrichment of Planetary Systems from Asymptotic Giant Branch Stars [PDF]
The Astrophysical Journal Letters, 2023 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 interstellar medium.

Turbulent Dynamo in Asymptotic Giant Branch Stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 Using recent results on the operation of turbulent dynamos, we show that a turbulent dynamo can amplify a large scale magnetic field in the envelopes of asymptotic giant branch (AGB) stars.

STARDUST FROM ASYMPTOTIC GIANT BRANCH STARS [PDF]
The Astrophysical Journal, 2009 The formation of dust in the outflows of low- and intermediate-mass stars on the first giant branch and asymptotic giant branch (AGB) is studied and the relative contributions of stars of different initial masses and metallicities to the interstellar medium (ISM) at the instant of solar system formation are derived.

Extremely Metal-Poor Asymptotic Giant Branch Stars [PDF]
Universe, 2022 Little is known about the first stars, but hints on this stellar population can be derived from the peculiar chemical composition of the most metal-poor objects in the Milky Way and in resolved stellar populations of nearby galaxies.

The Galactic distribution of asymptotic giant branch stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We study the Galactic distribution of ~10,000 Asymptotic Giant Branch (AGB) stars selected by IRAS colors and variability index. The distance to each star is estimated by assuming a narrow luminosity function and a model-derived bolometric correction.

An HI Imaging Survey of Asymptotic Giant Branch Stars [PDF]
, 2013 We present an imaging study of a sample of eight asymptotic giant branch (AGB) stars in the HI 21-cm line. Using observations from the Very Large Array, we have unambiguously detected HI emission associated with the extended circumstellar envelopes of ...

Updated stellar yields from Asymptotic Giant Branch models [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 An updated grid of stellar yields for low to intermediate-mass thermally-pulsing Asymptotic Giant Branch (AGB) stars are presented. The models cover a range in metallicity Z = 0.02, 0.008, 0.004, and 0.0001, and masses between 1Msun to 6Msun.

Crystallinity versus mass-loss rate in Asymptotic Giant Branch stars [PDF]
, 2001 Infrared Space Observatory (ISO) observations have shown that O-rich Asymptotic Giant Branch (AGB) stars exhibit crystalline silicate features in their spectra only if their mass-loss rate is higher than a certain threshold value.
