Planetary Engulfment Prognosis within the ρ CrB System
The Astrophysical Journal, 2023 Exoplanets have been detected around stars at various stages of their lives, ranging from young stars emerging from formation to the latter stages of evolution, including white dwarfs and neutron stars.

Properties of the Variation of the Infrared Emission of OH/IR Stars III. The M Band Light Curves [PDF]
Journal of Astronomy and Space Sciences, 2010 To study properties of the pulsation in the infrared emission for long period variables, we have collected and analyzed the infrared observational data at M band for 12 OH/IR stars.

Blue Stragglers After the Main Sequence [PDF]
, 2008 We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases.

Studying Asymptotic Giant Branch Stars in the JWST Era
Universe, 2020 We explore the potential offered by the incoming launch of the James Webb Space Telescope, to study the stars evolving through the asymptotic giant branch (AGB) phase. To this aim we compare data of AGB stars in the Large Magellanic Cloud, taken with the

On the missing second generation AGB stars in NGC 6752 [PDF]
, 2014 In recent years the view of Galactic globular clusters as simple stellar populations has changed dramatically, it is now thought that basically all globular clusters host multiple stellar populations, each with its own chemical abundance pattern and ...

A population of binaries in the Asymptotic Giant Branch of 47 Tucanae? [PDF]
, 2006 We have used a set of archived Hubble Space Telescope/ACS images to probe the evolved populations of the globular cluster 47 Tucanae. We find an excess of Asymptotic Giant Branch (AGB) stars in the cluster core. We interpret this feature as the signature

Evolution of Asymptotic Giant Branch Stars [PDF]
Annual Review of Astronomy and Astrophysics, 2005 ▪ Abstract The current status of modeling the evolution and nucleosynthesis of asymptotic giant branch (AGB) stars is reviewed. The principles of AGB evolution have been investigated in recent years leading to improved and refined models, for example with regard to hot-bottom burning or the third dredge-up.

The intermediate neutron-capture process in AGB stars [PDF]
EPJ Web of Conferences, 2023 The intermediate neutron-capture process is thought to arise when protons are mixed in a convective helium-burning zone. This can happen during the early Thermally-Pulsing (TP) Asymptotic Giant Branch (AGB) phase of low-mass, low-metallicity stars. After

Multiple populations along the asymptotic giant branch of the globular cluster M 4 [PDF]
, 2016 Nearly all Galactic globular clusters host stars that display characteristic abundance anti-correlations, like the O-rich/Na-poor pattern typical of field halo stars, together with O-poor/Na-rich additional components.
