Nucleosynthesis in low-mass stars: Shedding light on the cosmic origin of heavy elements [PDF]
EPJ Web of ConferencesLow-mass, low-metallicity stars while evolving through the asymptotic giant branch (AGB) phase undergo significant nucleosynthesis producing the majority of slow (s-) and intermedite (i-) neutron capture elements.

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 ...

Mass Losing Asymptotic Giant Branch Stars And Supergiants
, 2016 This paper presents a summary of four invited and twelve contributed presentations on asymptotic giant branch stars and red supergiants, given over the course of two afternoon splinter sessions at the 19th Cool Stars Workshop. It highlights both recent observations and recent theory, with some emphasis on high spatial resolution, over a wide range of ...

First giant branch and asymptotic giant branch stars in nearby aggregates
The Astronomical Journal, 1991 The properties of the brightest red stars in several aggregates in the Galaxy are compared with theoretical models. 22 asymptotic giant branch (AGB) stars are identified, four of which are in the thermally pulsing AGB (TPAGB) phase and four of which are TPAGB carbon stars.

Edge of Chaos Theory Unveils the First and Simplest Ever Reported Hodgkin–Huxley Neuristor
Advanced Electronic Materials, Volume 11, Issue 8, June 2025.This manuscript presents the first and simplest ever‐reported electrical cell, which leverages one memristor on Edge of Chaos to reproduce the three‐bifurcation cascade, marking the entire life cycle from birth to extinction via All‐to‐None effect of an electrical spike, also referred to as Action Potential, across axon membranes under monotonic ...

Parameterising the Third Dredge-up in Asymptotic Giant Branch Stars [PDF]
Publications Astronomical Society of Australia, 2002 We present new evolutionary sequences for low and intermediate mass stars (1−6M ⊙) for three different metallicities, Z = 0.02, 0.008, and 0.004. We evolve the models from the pre-main sequence to the thermally-pulsing asymptotic giant branch phase.

Spectral evolution of asymptotic giant branch stars
The Astrophysical Journal, 1988 L'evolution des etoiles de masse intermediaire de la branche geante asymptotique est simulee numeriquement a partir d'un modele de perte de masse simple. Les resultats sont compares aux donnees photometriques et spectrometriques enregistrees par le satellite IRAS dans le domaine ...

The Radio Wave Polarization of Saturn Lightning Observed by Cassini
Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.Abstract We investigate the polarization of the radio waves emitted by lightning in Saturn's atmosphere, which are referred to as SEDs for Saturn Electrostatic Discharges. Using the complete SED data set retrieved by Cassini's RPWS (Radio and Plasma Wave Science) instrument we found that the circular polarization of SEDs below a frequency of 2 MHz ...

Envelope loss of RGB/AGB stars and the formation of hot subdwarfs
EPJ Web of Conferences, 2013 Low mass stars may lose their envelopes in the first giant branch (RGB) or the asymptotic giant branch (AGB) via envelope ejection (i.e. superwind). The envelope loss of AGB stars leads to the formation of carbon-oxygen (CO) white dwarfs (WDs), while the
