Chemical evolution with rotating massive star yields - I. The solar neighbourhood and the s-process elements [PDF]
, 2018 We present a comprehensive study of the abundance evolution of the elements from H to U in the Milky Way halo and local disk. We use a consistent chemical evolution model, metallicity dependent isotopic yields from low and intermediate mass stars and ...

Discovery of s-process enhanced stars in the LAMOST survey [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Here we present the discovery of 895 s-process-rich candidates from 454 180 giant stars observed by the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) using a data-driven approach.

New s-process Mechanism in Rapidly Rotating Massive Population II Stars [PDF]
Astrophysical Journal, 2019 We report a new mechanism for the s-process in rotating massive metal-poor stars. Our models show that above a critical rotation speed, such stars evolve in a quasi-chemically homogeneous fashion, which gives rise to a prolific s-process.

Yuanzineng kexue jishu, 2023 The origin of elements in the universe is a basic scientific problem. The slow neutron capture process (s-process) is believed to be responsible for the nucleosynthesis of about half of the elements heavier than iron.

Non-standard s-process in massive rotating stars [PDF]
Astronomy & Astrophysics, 2018 Context. Recent studies show that rotation significantly affects the s-process in massive stars. Aims. We provide tables of yields for non-rotating and rotating massive stars between 10 and 150 M⊙ at Z = 10−3 ([Fe/H] = −1.8).

Study of the Briquetting Process of Walnut Shells for Pyrolysis and Combustion
Applied Sciences, 2023 Walnut shells can be used as fuels in power plants directly or as biochars obtained by pyrolysis or torrefaction. They are an example of clean waste biomass which shows a low ash content and a high Net Calorific Value, making them excellent for energy ...

The s process in AGB stars as constrained by a large sample of barium stars [PDF]
Astronomy & Astrophysics, 2018 Context. Barium (Ba) stars are dwarf and giant stars enriched in elements heavier than iron produced by the slow neutron-capture process (s process).

Separations, 2023 In this research, the adsorption of gallium onto natural zeolite (clinoptilolite) and two mesoporous-activated carbons were compared and evaluated. The clinoptilolite was treated with HCl (HCPL), while mesoporous-activated carbons (MCSG60A and MCO1) were
