Model Dust Envelopes for Asymptotic Giant Branch Stars. I. OH/IR Stars [PDF]
Journal of Astronomy and Space Sciences, 1995 OH/IR stars are the most massive and youngest subclass in asymptotic giant branch stars which pass through sporadic superwind phases. We have modeled the dust envelopes around OH/IR stars with close attention to the evolution of the structure of the dust

Post-Asymptotic Giant Branch Evolution of Low- and Intermediate-Mass Stars. Preliminary Results [PDF]
, 2014 Preliminary results from an ongoing project to compute a grid of post-AGB models is presented. Our preliminary results show that stellar evolution computations that include an updated treatment of the microphysics predict post-AGB timescales that are ...

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 ...

Large Deviations of the Giant Component in Scale‐Free Inhomogeneous Random Graphs
Random Structures &Algorithms, Volume 68, Issue 4, July 2026.ABSTRACT We study large deviations of the size of the largest connected component in a general class of inhomogeneous random graphs with iid weights, parametrized so that the degree distribution is regularly varying. We derive a large‐deviation principle with logarithmic speed: the rare event that the largest component contains linearly more vertices ...

Isotopic Enrichment of Planetary Systems from Asymptotic Giant Branch Stars
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.

Reconnaissance with JWST of the J-region Asymptotic Giant Branch in Distance Ladder Galaxies: From Irregular Luminosity Functions to Approximation of the Hubble Constant [PDF]
Astrophysical JournalWe study stars in the J-regions of the asymptotic giant branch (JAGB) of near-infrared color–magnitude diagrams in the maser host NGC 4258 and four hosts of six Type Ia supernovae (SNe Ia): NGC 1448, NGC 1559, NGC 5584, and NGC 5643.

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.

Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1593-1609, July 2026.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Model Dust Envelopes for Asymptotic Giant Branch Stars. Carbon Stars. II. Carbon Stars [PDF]
Journal of Astronomy and Space Sciences, 1995 We have modeled the dust envelopes around carbon stars with close attention to the evolution of the structure of the dust shells. We use various dust density distributions to take account the effect of the superwind due to the helium shell flash by ...
