Asymptotic Giant Branch Variables in Nearby Galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2018
AbstractCertain types of large amplitude AGB variable are proving to be powerful distance indicators that will rival Cepheids in the James Webb Space Telescope era of high precision infrared photometry. These are predominantly found in old populations and have low mass progenitors.

Study of ambient environment around Asymptotic Giant Branch Carbon Star: IRAS 01142+6306

open access: yesBibechana, 2018
We studied dust environment such as flux, temperature, mass and inclination angle of the cavity structure around the C-rich Asymptotic giant branch star in 60 μm and 100 μm wavelengths band using Infrared Astronomical Survey. We observed the data of AGB

WOCS 4540: Detailed Analysis of a very Long Orbital Period Blue Straggler

open access: yesThe Astrophysical Journal, 2023
WOCS 4540 is the longest orbital period ( P _orb = 3030 days) blue straggler star (BSS)—white dwarf (WD) pair in the old open cluster NGC 188. It also contains one of the most luminous BSS in the cluster.

CARBON-RICH DUST PAST THE ASYMPTOTIC GIANT BRANCH: ALIPHATICS, AROMATICS, AND FULLERENES IN THE MAGELLANIC CLOUDS [PDF]

open access: yes, 2014
Infrared spectra of carbon-rich objects that have evolved off the asymptotic giant branch reveal a range of dust properties, including fullerenes, polycyclic aromatic hydrocarbons (PAHs), aliphatic hydrocarbons, and several unidentified features ...

New light on Galactic post-asymptotic giant branch stars - I. First distance catalogue [PDF]

open access: yes, 2014
We have commenced a detailed analysis of the known sample of Galactic post-asymptotic giant branch (PAGB) objects compiled in the Toru´ n catalogue of Szczerba et al., and present, for the first time, homogeneously derived distance determinations for the

EVOLUTION OF THERMALLY PULSING ASYMPTOTIC GIANT BRANCH STARS. IV. CONSTRAINING MASS LOSS AND LIFETIMES OF LOW MASS, LOW METALLICITY AGB STARS [PDF]

open access: yes, 2014
The evolution and lifetimes of thermally pulsating asymptotic giant branch (TP-AGB) stars suffer from significant uncertainties. In this work, we analyze the numbers and luminosity functions of TP-AGB stars in six quiescent, low metallicity ([Fe/H] ≲ −0 ...

Mass Losing Asymptotic Giant Branch Stars And Supergiants [PDF]

open access: yesarXiv: Solar and Stellar Astrophysics, 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 ...
