原恒星冰中雪线的位置

The Location of the Snow Line in Protostellar Disks

Morris Podolak

摘要:

气体盘中的雪线被定义为与恒星的距离,超过该距离,水冰就稳定地不蒸发。由于氧是氢和氦之后最丰富的元素,冰粒的存在对磁盘演化有重要影响。然而,确定雪线的位置并不简单。我将讨论一些影响雪线位置的重要过程。

英文摘要:

The snow line in a gas disk is defined as the distance from the star beyond which the water ice is stable against evaporation. Since oxygen is the most abundant element after hydrogen and helium, the presence of ice grains can have important consequences for disk evolution. However, determining the position of the snow line is not simple. I discuss some of the important processes that affect the position of the snow line.
