The environments of the 5000 nearest K Dwarf star systems will be explored to answer the question, "How does our Sun compare to other stars"? Surveys will be carried out to provide a detailed understanding of star and planetary formation processes. It will characterize how unique is our Sun and tell us how our Sun (a G Dwarf star) compares to other G,K,M Dwarf stars, provide fundamental statistics that will drive theoretical work on star and planet formation and provide a list of stars where other solar systems may be found, allowing future astrobiologists to evaluate the environment around these stars. Students will be involved in this research and gain STEM expertise in science, mathematics, computer science, and engineering through their participation in this research program. Novel observing programs on binary stars will be developed for the undergraduate students at Southern Connecticut State University. This program K-KIDs, a reconnaissance of the 5000 nearest K Dwarfs, will study the K dwarf stars using three surveys. A wide field survey to characterize companion stars, a high resolution speckle imaging survey to split single stars into doubles and higher order multiples at spatial scales similar to our Solar System, and a high resolution spectroscopic survey to reveal close stellar binaries and discover low mass brown dwarfs and Jovian planet companions and estimate metallicities and ages for the stars. This will allow the discovery of how unusual our Sun is, provide fundamental statistics on G,K and M Dwarf type stars for theoretical studies on star and planet formation, and provide a candidate list for locating other nearby solar systems in the galaxy.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

将探索5000个最近的K矮人恒星系统的环境，以回答“我们的太阳与其他恒星相比如何”的问题？ 将进行调查，以提供对恒星和行星形成过程的详细理解。它将表征我们的太阳是多么独特，并告诉我们如何与其他G，K，M矮人恒星进行比较，提供了基本的统计数据，这些统计数据将推动恒星和行星形成的理论工作，并提供可以找到其他太阳能系统的明星列表，从而使未来的天体学家可以评估这些星星周围的环境。 学生将参与这项研究，并通过参与该研究计划来获得科学，数学，计算机科学和工程学方面的STEM专业知识。 将为南部康涅狄格州立大学的本科生开发有关二进制明星的新观察计划。 该程序K-kids是对最近的K矮人的侦察，将使用三个调查研究K矮人的恒星。 一项旨在表征同伴恒星的广泛现场调查，一项高分辨率斑点成像调查，将单个恒星分为双打和高阶倍数在与我们的太阳能系统类似的空间尺度下，以及一项高分辨率光谱调查，以揭示近距离的恒星二进制文件，并发现低质量的棕色矮人矮人矮人和jovian Planet Planet Companions and Eastimate Companions and Eastimate Callimate Callimate and Estimate CallaLlicic and Exallice and Exallice and Ages and Allallalcions and Eges and Eges and Sars of Sarts of the Sarts。 这将允许发现我们的太阳有多不寻常，提供有关G，K和M矮人类型的明星的基本统计数据，用于恒星和星球形成的理论研究，并为在银河系中找到附近的其他太阳能系统提供了候选列表。该奖项反映了NSF的法定任务，反映了通过评估基金会的范围和宽广的基础构成和宽广的支持者，并已被认为是基金会的范围。
