THE INTERACTION OF ASYMPTOTIC GIANT BRANCH STARS WITH THE INTERSTELLAR MEDIUM [PDF]
The Astrophysical Journal, 2012 We study the hydrodynamical behavior of the gas expelled by moving Asymptotic Giant Branch Stars interacting with the ISM. Our models follow the wind modulations prescribed by stellar evolution calculations, and we cover a range of expected relative velocities (10 to 100 km/s), ISM densities (between 0.01 and 1 cm-3), and stellar progenitor masses (1 ...

Impact of AGB Stars on the Chemical Evolution of Neutron-Capture Elements
Universe, 2022 In this review, we discuss the impact of s-process nucleosynthesis in asymptotic giant branch stars on the enrichment of heavy elements. We review the main steps made on this subject in the last 40 years and discuss the importance of modelling the ...

Rubidium and zirconium abundances in massive Galactic asymptotic giant branch stars revisited [PDF]
, 2017 Luminous Galactic OH/IR stars have been identified as massive (>4-5 M_s) AGB stars experiencing HBB and Li production. Their Rb abundances and [Rb/Zr] ratios derived from hydrostatic model atmospheres, are significantly higher than predictions from AGB ...

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.

IDENTIFICATION OF A CLASS OF LOW-MASS ASYMPTOTIC GIANT BRANCH STARS STRUGGLING TO BECOME CARBON STARS IN THE MAGELLANIC CLOUDS [PDF]
, 2015 We have identified a new class of Asymptotic Giant Branch (AGB) stars in the Small and Large Magellanic Clouds (SMC/LMC) using optical to infrared photometry, light curves, and optical spectroscopy.

Luminosity Functions for Asymptotic Giant Branch Stars [PDF]
Symposium - International Astronomical Union, 1984 To understand the evolution of carbon and oxygen rich asymptotic giant branch (AGB) stars it is important to observationally establish the relations between parameters such as luminosity, age, and metallicity. The existence of luminous (brighter than the top of the first giant branch) AGB stars in clusters in the Magellanic Clouds (Mould and Aaronson ...

The Large Magellanic Cloud as a laboratory for hot bottom burning in massive asymptotic giant branch stars [PDF]
, 2015 We use Spitzer observations of the rich population of Asymptotic Giant Branch stars in the Large Magellanic Cloud (LMC) to test models describing the internal structure and nucleosynthesis of the most massive of these stars, i.e.

Asymptotic Giant Branch Stars in the Magellanic Clouds [PDF]
Symposium - International Astronomical Union, 1991 Since the pioneering objective prism surveys by Westerlund (1960) and Blanco et al. (1980), the Magellanic Clouds have proved a fruitful site for exploring the evolution of AGB stars. We have used photometric techniques to extend the prism C-star surveys to M- and S-type AGB stars, constructing luminosity functions and obtaining spectra of individual ...

An Innovative Tool for Measuring Sunlight Propagation Through Different Snowpacks
Earth and Space Science, Volume 12, Issue 8, August 2025.Abstract Sunlight penetration in the snowpack plays a fundamental role in many environmental processes, ranging from local energy balance to snow microbiology and can potentially contribute to climate change. In addition, many photochemical reactions typically occur in the snowpack driven by solar radiation.
