Challenges in nucleosynthesis of trans-iron elements

AIP Advances, 2014
Nucleosynthesis beyond Fe poses additional challenges not encountered when studying astrophysical processes involving light nuclei. Astrophysical sites and conditions are not well known for some of the processes involved.

A mechanism to account for well known peculiarities of low mass AGB star nucleosynthesis

EPJ Web of Conferences, 2017
We present here the application of a model for a mass circulation mechanism induced by the stellar magnetic field to study peculiar aspects of AGB star nucleosynthesis. The mixing scheme is based on a previously suggested magnetic-buoyancy process [1, 2]

The status and future of direct nuclear reaction measurements for stellar burning

, 2022
The study of stellar burning began just over 100 years ago. Nonetheless, we do not yet have a detailed picture of the nucleosynthesis within stars and how nucleosynthesis impacts stellar structure and the remnants of stellar evolution.

Stellar Mixing and s-PROCESS Nucleosynthesis

The Astrophysical Journal, 1977
A model for the operation of the s-process is studied in which neutron capture occurs only in a thin layer at the bottom of a deep convective envelope. Simultaneous convective mixing and neutron capture are described by means of diffusion equations. We find that this model admits abundance distributions which resemble the solar system distribution, but

Re-examining Neutron Capture and Stellar Weak Rates of 97Mo under Astrophysical Conditions

Cumhuriyet Science Journal
This paper presents a re-analysis of neutron capture and stellar weak interaction rates of 97Mo under astrophysical conditions. The Maxwellian-averaged cross sections (MACS), neutron capture rates, and β^- decay/positron capture rates are investigated ...

Role of clusters in nuclear astrophysics with Cluster Nucleosynthesis Diagram (CND)

, 2013
The role of nuclear clustering in stellar reactions is discussed, with Cluster Nucleosynthesis Diagram (CND) proposed before, for nucleosynthesis in stellar evolution and explosive stellar phenomena.
