Theron Carmichael is awarded a Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship (MPS-Ascend) to conduct a program of research and education at the University of Hawai’i, Manoa. He plans to study the population of transiting brown dwarfs, which are rare objects that serve as the bridge between planets and stars in the Milky Way galaxy. He will serve as a mentor in the Research Experience for Teachers (RET) and the Hawai’i Student/Teacher Astronomy Research (HI STAR) programs at Manoa to improve the participation of students from the Native Hawaiian community and other underrepresented backgrounds in astronomy research.Carmichael will take measurements of the masses, radii, and ages of newly discovered transiting brown dwarfs in order to gain a deeper understanding of their formation mechanisms and evolution. These measurements will be compared against substellar evolution models that aim to predict how brown dwarf masses and radii evolve over time. Through this work, Carmichael will explore the mass range at which brown dwarfs stop forming the way giant planets do and begin to form more like stars. He will additionally explore the effects of stellar irradiation on the radius evolution of transiting brown dwarfs. Carmichael plans to mentor and advise junior researchers using brown dwarf science as a rich learning environment for these young scientists to grow. He will use his past experience in mentorship roles to help these scientists identify, understand, and overcome the systemic barriers they may face as they become full-fledged researchers and future leaders in astronomy.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.

塞隆·卡迈克尔（Theron Carmichael）被授予一项数学和物理科学，上升博士后研究奖学金（MPS-ASCEND），以在Manoa夏威夷大学进行研究和教育计划。他计划研究过境的棕色矮人的人口，这些矮人是罕见的物体，在银河系中充当行星和恒星之间的桥梁。 He will serve as a mental in the Research Experience for Teachers (RET) and the Hawai’i Student/Teacher Astronomy Research (HI STAR) programs at Manoa to improve the participation of students from the Native Hawaiian community and other underlying backgrounds in astronomy research.Carmichael will take measurements of the masses, radii, and ages of newly discovered transiting brown dwarfs in order to gain a deeper understanding of their formation mechanisms and evolution.这些测量结果将与旨在预测棕色矮人质量和半径演化的旨在随着时间的流逝进行比较。通过这项工作，Carmichael将探索Brown Dwarfs停止形成巨型行星所做的方式并开始形成更像恒星的质量范围。他还将探索恒星辐照对过境棕色矮人半径演变的影响。 Carmichael计划使用Brown Dwarf Science作为精神和顾问研究人员，作为这些年轻科学家成长的丰富学习环境。他将利用自己过去在心态角色的经验来帮助这些科学家确定，理解和克服他们成为成熟的研究人员和未来的天文学领导者时可能面临的系统性障碍。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛的影响审查审查标准来通过评估来获得的支持。
