The NuGrid AGB Evolution and Nucleosynthesis Data Set
Universe, 2022 Asymptotic Giant Branch (AGB) stars play a key role in the chemical evolution of galaxies. These stars are the fundamental stellar site for the production of light elements such as C, N and F, and half of the elements heavier than Fe via the slow neutron

Sliding along the Eddington Limit—Heavy-Weight Central Stars of Planetary Nebulae
Galaxies, 2018 Due to thermal pulses, asymptotic giant branch (AGB) stars experience periods of convective mixing that provide ideal conditions for slow neutron-capture nucleosynthesis.

Mixing and Magnetic Fields in Asymptotic Giant Branch Stars in the Framework of FRUITY Models
Universe, 2021 In the last few years, the modeling of asymptotic giant branch (AGB) stars has been much investigated, both focusing on nucleosynthesis and stellar evolution aspects. Recent advances in the input physics required for stellar computations made it possible

Variability in Protoplanetary Nebulae. X. Multiyear Periods as an Indicator of Potential Binaries
The Astronomical Journal, 2023 New observations are presented of four evolved objects that display long, multiyear variations in their light curves. These are interpreted as good evidence of their binary nature, with the modulation caused by the barycenter motion of the evolved star ...

Post-AGB Discs from Common-Envelope Evolution
Galaxies, 2018 Post-asymptotic giant branch (post-AGB) stars with discs are all binaries. Many of these binaries have orbital periods between 100 and 1000 days so cannot have avoided mass transfer between the AGB star and its companion, likely through a common-

Corporate Social Responsibility and Environmental Management, Volume 33, Issue 4, Page 5321-5346, July 2026.ABSTRACT Corporate social responsibility (CSR) has undergone continuous expansion across industries, yet its intellectual evolution and cross‐sectoral linkages remain insufficiently understood. This study provides a comprehensive, data‐driven assessment of CSR's developmental trajectories by analyzing 3314 Web of Science articles using key‐route main ...

Evidence of Third Dredge-up in Post-AGB Stars in Galactic Globular Clusters
The Astrophysical JournalTo better understand the mixing and mass loss experienced by low-mass stars as they ascend the asymptotic giant branch (AGB), I have gathered from the literature the abundances of CNO and s -process elements in post-AGB stars in Galactic globular ...

Systematic Search for Water Fountain Candidates Using the Databases of Circumstellar Maser Sources
The Astrophysical Journal Supplement SeriesWater fountains (WFs) are thought to be objects in the morphological evolution of the circumstellar envelopes of low- and intermediate-mass evolved stars, transitioning from spherically symmetric to asymmetric shapes.

The Astrophysical Journal, 2023 Some evolved binaries, namely post–asymptotic giant branch (AGB) binaries, are surrounded by stable and massive circumbinary disks similar to protoplanetary disks found around young stars. Around 10% of these disks are transition disks: they have a large
