This article reviews our current understanding of modelling convection dynamics in stars. Several semi-analytical time-dependent convection models have been proposed for pulsating one-dimensional stellar structures with different formulations for how the convective turbulent velocity field couples with the global stellar oscillations. In this review we put emphasis on two, widely used, time-dependent convection formulations for estimating pulsation properties in one-dimensional stellar models. Applications to pulsating stars are presented with results for oscillation properties, such as the effects of convection dynamics on the oscillation frequencies, or the stability of pulsation modes, in classical pulsators and in stars supporting solar-type oscillations.

对流与脉动之间的相互作用

本文回顾了我们目前对恒星对流动力学建模的理解。对于对流湍流场如何与整体恒星振荡耦合,已经提出了几种半解析时间相关的对流模型,用于对具有不同公式的一维恒星结构进行脉动。在这篇综述中,我们重点介绍了两种广泛使用的,时间相关的对流公式,用于估算一维恒星模型中的脉动特性。介绍了在脉动星的应用中获得的振荡特性的结果,例如对流动力学对振荡频率的影响,或经典波轮和支持太阳型振荡的恒星对脉动模式的稳定性的影响。
