Dr. Brittain will lead and carry out a project that will enhance our understanding of the process of planet formation by studying gas in the inner region of circumstellar disks. While it is accepted that planetary systems form out of the gas and dust seen around newly formed stars, fundamental questions remain about this process. This project will study the planet-forming region of circumstellar disks using high-resolution infrared spectroscopy. This study will be able to measure the amounts of warm gas present in these disks and will help constrain the timescales for gas dissipation which is likely related to how quickly gas giant planets like Jupiter can form.The Broader Impacts of this proposal are centered on attracting, developing, and retaining a diverse group of students to the sciences. The PI proposes to develop astronomy related workshops for disadvantaged students through the collaboration of elementary education and physics majors at Clemson. The students come from the 'Creative Inquiry Initiative' program (which is already established at active at Clemson) which matches teams of students with a faculty mentor for a five semester project. Additionally, the research proposed here will make up a significant portion of a Clemson student?s Ph.D. Dissertation.

布里顿博士将领导和开展一个项目，通过研究星周盘内部区域的气体，提高我们对行星形成过程的理解。虽然人们普遍认为行星系统是由新形成恒星周围的气体和尘埃形成的，但关于这一过程的根本问题仍然存在。该项目将利用高分辨率红外光谱学研究星周盘的行星形成区域。这项研究将能够测量这些盘中存在的温暖气体的数量，并将有助于限制气体消散的时间尺度，这可能与木星等气体巨行星形成的速度有关。这项提议的更广泛影响集中在吸引，发展和保留不同的学生群体。PI建议通过克莱姆森小学教育和物理专业的合作，为弱势学生举办天文学相关讲习班。这些学生来自“创造性探究倡议”项目（该项目已经在克莱姆森成立），该项目将学生团队与教师导师进行五个学期的项目匹配。此外，这里提出的研究将构成一个克莱姆森学生的重要组成部分？博士学位论文。
