Physical Processes Responsible for Heating and Wind Acceleration in Solar Coronal Holes

该项目将讨论日冕洞中加热和风加速的物理过程。为了确定哪种机制在向日冕洞提供波能方面起主导作用，PI将计算在太阳对流带顶部附近存在的大幅度声波产生阿尔文管波的效率。然后将计算的波能通量与先前获得的波能通量以及观测所需的总热输入进行比较。这些研究对于理解日冕洞的主要能量来源和创造日光层的基本物理过程将是重要的。

This project will address the physical processes responsible for the heating and wind acceleration in solar coronal holes. To determine which mechanism is dominant in supplying the wave energy to solar coronal holes, the PI will calculate the efficiency of generation of Alfven tube waves by large amplitude acoustic waves existing near the top of the solar convective zone. The calculated wave energy fluxes will then be compared to those obtained earlier, and to the total heat input required by observations. These studies will be important to understanding the principal energy sources for solar coronal holes and the basic physical processes responsible for creating the heliosphere.***
