The Role of Dust in Defining the Structure of Red Giant Winds

在它们活跃的生命结束时，大多数恒星变得很大， 又冷又亮的红巨星 当他们完成这个阶段，许多开始 通过被称为风的外流失去它们的外层。 是 我认为驱动这些风的一个重要因素是 形成通常称为粉尘的小固体颗粒。 这种尘埃在推动外流和 将研究这种外流的动态。 调查 还将进行的影响，风的存在 有一个双星伴星 亚毫米 将进行观测以验证某些预测 的理论。 由于红巨星的强风完全 改变恒星的演化，并提供丰富的物质， 星际介质，这项工作具有广泛的影响， 天文学的几个领域。

At the end of their active lives, most stars become large, very cool but bright red giants. As they finish this stage, many begin to lose their outer layers through outflows known as winds. It is thought that an important factor driving these winds is the formation of small solid particles commonly referred to as dust. The role played by this dust in driving the outflow and the dynamics of such outflows will be investigated. An investigation will also be conducted of the effects on the wind of the presence of a binary companion to the star in question. Submillimeter observations will be undertaken to verify some of the predictions of the theory. Since the strong winds from red giants completely alter the evolution of the stars and provide enriched material to the interstellar medium, this work has broad ramifications to several areas of astronomy.
