标题： Two-component jet simulations: II. Combining analytical disk and stellar MHD outflow solutions

摘要： 理论论证以及YSO喷流的观测数据表明存在两个稳定的组分：一种是盘风类型的流出，用于解释观测到的高质量损失率，另一种是恒星风类型的流出，可能负责观测到的恒星自转减慢。 每个组分的贡献取决于YSO-盘系统的固有物理特性和其演化阶段。 本文的主要目标是理解在参数空间内以及当时间变化被强制时，这两个喷流组分的演化、相互作用和共存的一些基本特征。 在本系列论文的第一篇中，我们分别研究了互补盘和恒星解析风解的数值演化，此处我们继续在计算箱内将两种模型混合在一起。 时间演化使用PLUTO代码进行，研究双组分喷流的动力学，每个解所经历的修改以及可能达到的稳定状态。 显示英文摘要

摘要： Theoretical arguments along with observational data of YSO jets suggest the presence of two steady components: a disk wind type outflow needed to explain the observed high mass loss rates and a stellar wind type outflow probably accounting for the observed stellar spin down. Each component's contribution depends on the intrinsic physical properties of the YSO-disk system and its evolutionary stage. The main goal of this paper is to understand some of the basic features of the evolution, interaction and co-existence of the two jet components over a parameter space and when time variability is enforced. Having studied separately the numerical evolution of each type of the complementary disk and stellar analytical wind solutions in Paper I of this series, we proceed here to mix together the two models inside the computational box. The evolution in time is performed with the PLUTO code, investigating the dynamics of the two-component jets, the modifications each solution undergoes and the potential steady state reached.
