This award will provide partial support for a conference in the area of stellar polarimetry, or the measurement of polarized light from stars or their surroundings. Polarization is the alignment of the orientation of the oscillations of electromagnetic waves (visible light, infrared, radio waves), and is a powerful indicator of physical conditions such as light scattering from grains or population inversions from non-thermal processes. Historically, studies of polarization have not been very popular, mainly because they are somewhat difficult to perform and calibrate, and generally are done best on bright sources. This conference will address current and future directions in polarimetry studies, especially in the context of observations on large telescopes. The discussions will focus on three areas, namely on stellar magnetism, the geometry of light scattering, and the exploration of opacity sources in stellar atmospheres.

该奖项将为恒星偏振测量领域的会议提供部分支持，或测量恒星或其周围环境的偏振光。 偏振是电磁波（可见光，红外线，无线电波）振荡方向的对齐，并且是物理条件的有力指标，如颗粒的光散射或非热过程的粒子数反转。 从历史上看，偏振的研究并不是很流行，主要是因为它们有点难以执行和校准，并且通常在明亮的光源上做得最好。 本次会议将讨论偏振测量研究的当前和未来方向，特别是在大型望远镜观测的背景下。讨论将集中在三个领域，即恒星磁性，光散射的几何形状，恒星大气中的不透明度源的探索。
