Nucleosynthesis, Mixing Processes, and Gas Pollution from AGB Stars

open access: yesUniverse, 2022
We discuss the evolution of stars through the asymptotic giant branch, focusing on the physical mechanisms potentially able to alter the surface chemical composition and on how changes in the chemistry of the external regions affect the physical ...

The Interaction Between Accretion from the Interstellar Medium and Accretion from the Evolved Binary Component in Barium Stars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2018
The reanalysis of the previously published abundance pattern of mild barium star HD202109 (ζ Cyg) and the chemical compositions of 129 thin disk barium stars facilitated the search for possible correlations of different stellar parameters with second ...

Abundance

open access: yes, 2023
The objective world subsists, functions, and plays its follies according to the temporal dominion and phenomenal laws over which man has no control – just as he has no control over laws of gravitation (Nevatia and Nevatia 2021). The generally accepted notion is that the economy operates under conditions of scarcity, whereby resources that are limited ...

Structure formation cosmic rays: Identifying observational constraints [PDF]

open access: yesSerbian Astronomical Journal, 2005
Shocks that arise from baryonic in-fall and merger events during the structure formation are believed to be a source of cosmic rays. These "structure formation cosmic rays" (SFCRs) would essentially be primordial in composition, namely, mostly made of ...

Magellanic Clouds Cepheids: Thorium Abundances [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2018
The analysis of the high-resolution spectra of 31 Magellanic Clouds Cepheid variables enabled the identification of thorium lines. The abundances of thorium were found with spectrum synthesis method. The calculated thorium abundances exhibit correlations

The Record-Warm Barents Sea and 0-Group Fish Response to Abnormal Conditions

open access: yesFrontiers in Marine Science, 2020
The Barents Sea is a nursery area for many commercially and ecologically important fish stocks, and this whole region is presently subject to rapid climatic change from a cold period in the 1980s to a record warm period in the latest decade, with a peak ...

Indirect Measurements of n- and p-Induced Reactions of Astrophysical Interest on Oxygen Isotopes

open access: yesFrontiers in Astronomy and Space Sciences, 2020
Observations of abundances and isotopic ratio determinations in stars yield powerful constraints on stellar models. In particular, the oxygen isotopic ratios are of particular interest because they are affected not only by nucleosynthesis but also by ...
