摘要

本文综述了一维混合长度理论(MLT)对流模型在恒星内部和低质量恒星演化中的应用。我们总结了MLT的历史,在一维恒星结构方程的背景下给出了MLT的推导,并讨论了与MLT相关的物理机制。我们回顾了改进和扩展形式主义的尝试,包括更高的维度。我们讨论了MLT与其他模拟物理的相互作用,并演示了引入对流混合长度αMLT变化对恒星轨道和等时线的影响。我们总结了对αMLT进行太阳校准的过程以及对非太阳目标进行校准的最新进展。我们讨论了改变混合长度的科学含义,使用最近的分析来证明。我们回顾了MLT最突出的成功,以及剩下的挑战,我们通过推测对流处理的未来来结束。

A Review of the Mixing Length Theory of Convection in 1D Stellar Modeling
We review the application of the one-dimensional Mixing Length Theory (MLT) model of convection in stellar interiors and low-mass stellar evolution. We summarize the history of MLT, present a derivation of MLT in the context of 1D stellar structure equations, and discuss the physical regimes in which MLT is relevant. We review attempts to improve and extend the formalism, including to higher dimensions. We discuss the interactions of MLT with other modeling physics, and demonstrate the impact of introducing variations in the convective mixing length, αMLT, on stellar tracks and isochrones. We summarize the process of performing a solar calibration of αMLT and state-of-the-art on calibrations to non-solar targets. We discuss the scientific implications of changing the mixing length, using recent analyses for demonstration. We review the most prominent successes of MLT, and the remaining challenges, and we conclude by speculating on the future of this treatment of convection.
