An Empirical formula for the mass-loss rates of dust-enshrouded red supergiants and oxygen-rich asymptotic giant branch stars [PDF]

, 2005
We present an empirical determination of the mass-loss rate as a function of stellar luminosity and effective tem- perature, for oxygen-rich dust-enshrouded Asymptotic Giant Branch stars and red supergiants.

Thermally Pulsing Asymptotic Giant Branch Star Models and Globular Cluster Planetary Nebulae I: The Model

, 2011
Thermally pulsing asymptotic giant branch models of globular cluster stars are calculated using a synthetic model with the goal of reproducing the chemical composition, core masses and other observational parameters of the four known globular cluster ...

Evolution of the dust mass loss with luminosity along the giant branch of the globular cluster 47 Tuc [PDF]

, 2001
The paper investigates the properties of the dust mass loss in stars populating the giant branch of the globular cluster 47 Tuc, by combining ISOCAM and DENIS data. Raster maps of 5 fields covering areas ranging from 4 x 4 to 15 x 15 arcmin2 at different

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.

Imputation of Fisheries Reference Points for Endangered Data‐Poor Fishes, With Application to Rhino Rays

Fish and Fisheries, Volume 26, Issue 5, Page 848-865, September 2025.
ABSTRACT For data‐limited fish species, sustainable management frequently relies on biological metrics that are derived from life‐history trait data, as opposed to high‐resolution time series of catch and abundance. These biological metrics are used to assess a species' recovery potential at low population densities, as well as their extinction risk ...

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

The Isaac Newton Telescope Monitoring project: Stellar population in the IC 10 dwarf irregular galaxy [PDF]

Iranian Journal of Astronomy and Astrophysics, 2019
We have conducted an optical monitoring survey of IC 10 dwarf irregular galaxy in the Local Group, using the Isaac Newton Telescope (INT) with the wide-field camera (WFC), to identify the Asymptotic Giant Branch stars (AGBs).

Trojan Horse Investigation for AGB Stellar Nucleosynthesis

Universe, 2022
Asymptotic Giant Branch (AGB) stars are among the most important astrophysical sites influencing the nucleosynthesis and the chemical abundances in the Universe. From a pure nuclear point of view, several processes take part during this peculiar stage of

, 2012
We present O, Na, and Fe abundances, as well as radial velocities, for 113 red giant branch (RGB) and asymptotic giant branch (AGB) stars in the globular cluster M13.

LOST AND FOUND: EVIDENCE OF SECOND-GENERATION STARS ALONG THE ASYMPTOTIC GIANT BRANCH OF THE GLOBULAR CLUSTER NGC 6752 [PDF]

, 2016
We derived chemical abundances for C, N, O, Na, Mg, and Al in 20 asymptotic giant branch (AGB) stars in the globular cluster (GC) NGC 6752. All these elements (but Mg) show intrinsic star-to-star variations and statistically significant correlations or ...
