Stellar Evolution Constraints on the Triple-Alpha Reaction Rate
Stellar Evolution Constraints Triple-Alpha Reaction Rate
2011/10/19
We investigate the quantitative constraint on the triple-alpha reaction rate based on stellar evolution theory, motivated by the recent significant revision of the rate proposed by nuclear physics cal...
Revision of the 15N(p,γ)16O reaction rate and oxygen abundance in H-burning zones
physical data processes: nuclear reactions abundances
2011/10/13
The NO cycle takes place in the deepest layer of a H-burning core or shell, when the temperature exceeds T {\simeq} 30 {\cdot} 106 K. The O depletion observed in some globular cluster giant stars, alw...
Reaction Networks For Interstellar Chemical Modelling: Improvements and Challenges
Reaction Networks Interstellar Chemical Modelling
2010/11/11
We survey the current situation regarding chemical modelling of the synthesis of molecules in the interstellar medium. The present state of knowledge concerning the rate coecients and their uncertain...
The Effect of Screening Factors and Thermonuclear Reaction Rates in the Pre-main Sequence Evolution of Low Mass Stars
Low mass stars thermonuclear reaction rates electron screening factors composition changes
2010/9/15
In understanding the nucleosynthesis of the elements in stars,one of the most important quantities is the reaction rate and it must be evaluated in terms of the stellar temperature T , and its determi...
