The researchers conduct millimeter-wavelength interferometry of CO (and related isotopologues) gas and dust emission from circumstellar disks that are at different stages of growth. The PI and his research team will also model the molecular chemistry and radiative transfer for each disk in order to estimate mass as a function of time. The new mass estimates will be used to constrain models of disk and planetary formation and evolution. He plans to use the Submillimeter Array (SMA) on Mauna Kea, and ALMA. A graduate student at University of Hawaii-Manoa, undergraduate student at University of Hawaii at Hilo and student in the Research Experiences for Undergraudates (REU) summer program will also participate in the research.

研究人员对处于不同生长阶段的室内磁盘的CO（及相关同位素）气体和尘埃发射的CO（及相关同位素）进行毫米波长的干涉量。 PI和他的研究团队还将对每个磁盘的分子化学和辐射转移进行建模，以估算质量作为时间的函数。新的质量估计将用于约束磁盘和行星形成和进化的模型。 他计划在Mauna Kea和Alma上使用亚毫米阵列（SMA）。 夏威夷大学的一名研究生，夏威夷大学希洛大学的本科生，以及在妇人的研究经验（REU）夏季计划的研究经验也将参加这项研究。
