This project involves the acquisition, analysis, and interpretation of observations of the near infrared solar corona, in an attempt to understand the relative contributions of electron scattering, dust scattering, and dust thermal emission near the Sun. The observations will be carried out from Mauna Kea, Hawaii utilizing a new eclipse coronograph system. The system is designed to observe the coronal signal in the infrared H and K bands, and at wavelengths in between, in polarized and unpolarized light, outside and during solar eclipse. Successful interpretation of the new observations should result in better understanding of the role of circumsolar and circumstellar dust grains, and in particular, should help resolve long-standing questions concerning the role of thermal emission by dust near the Sun. This award is made under the auspices of the Research in Undergraduate Institutions (RUI) program at the National Science Foundation.

该项目涉及近红外日冕观测数据的采集、分析和解释，试图了解太阳附近电子散射、尘埃散射和尘埃热发射的相对贡献。 这些观测将在夏威夷莫纳克亚山利用新的日食日冕仪系统进行。 该系统旨在观测红外 H 和 K 波段及其之间的波长、偏振光和非偏振光、日食外和日食期间的日冕信号。 对新观测结果的成功解释应该有助于更好地理解日周和星周尘埃颗粒的作用，特别是有助于解决有关太阳附近尘埃热发射作用的长期存在的问题。 该奖项是在美国国家科学基金会本科机构研究 (RUI) 项目的赞助下颁发的。
