非最小物质-曲率耦合引力中的Jeans不稳定性

Jeans Instability in Non-Minimal Matter-Curvature Coupling Gravity

Cláudio Gomes

摘要:

研究了非最小耦合Boltzmann方程的弱场极限,导出了不变的Barthmann标量势之间的关系。通过修正的色散关系,得到了不稳定性的Jean判据.特殊情况下进行审查和考虑的模型参数进行了讨论博克球。

英文摘要:

The weak field limit of the nonminimally coupled Boltzmann equation is studied, and relations between the invariant Bardeen scalar potentials are derived. The Jean's criterion for instabilities is found through the modified dispersion relation. Special cases are scrutinised and considerations on the model parameters are discussed for Bok globules.
