标题： Effects of rotation and surface forcing on deep stellar convection zones

摘要： 由于日震学结果和全球三维对流模拟，恒星对流的经典理解最近受到了质疑。 这个“对流难题”体现在模拟中的大尺度速度振幅远高于日震学结果，并且用全局三维模拟再现太阳差分自转和发电机机制存在困难。 这里从针对测试旋转影响和表面强迫对深层对流作用的水动力学笛卡尔三维模拟的角度讨论了这一难题的一些方面。 更具体地，详细讨论了对流的主要尺度、对流区的深度以及弱次绝热但仍对流的迪尔多夫区。 显示英文摘要

摘要： The canonical undestanding of stellar convection has recently been put under doubt due to helioseismic results and global 3D convection simulations. This "convective conundrum" is manifested by much higher velocity amplitudes in simulations at large scales in comparison to helioseismic results, and the difficulty in reproducing the solar differential rotation and dynamo with global 3D simulations. Here some aspects of this conundrum are discussed from the viewpoint of hydrodynamic Cartesian 3D simulations targeted at testing the rotational influence and surface forcing on deep convection. More specifically, the dominant scale of convection and the depths of the convection zone and the weakly subadiabatic -- yet convecting -- Deardorff zone are discussed in detail.
