In this project, Dr. Barsony and her collaborators will conduct an observational survey to search for sub-stellar or planetary-mass objects in regions of star formation. These objects, called T-dwarfs, are relatively luminous when young, and can be detected because they exhibit broad absorption features from methane in their spectra. The research team will conduct a wide-area infrared survey to find T-dwarfs by imaging at the wavelength of the methane band and at an adjacent wavelength. Objects that are faint in the methane band are likely to be T-dwarf stars.The research activity will have a broader educational impact through the involvement of undergraduate students in the research effort. Students will be recruited at San Francisco State University and at Utah Valley State College (now Utah Valley University), and will have the opportunity to visit the other institution in the collaboration. The detection of large numbers of T-dwarfs will help improve theories of star formation, especially in the domain between the least-massive stars and the most-massive planets.

在这个项目中，Barsony博士和她的合作者将进行一项观察性调查，以搜索恒星形成区域中的子赛车或行星质量对象。 这些称为T型瓦的物体在年轻时相对发光，因此可以检测到它们是因为它们在光谱中表现出巨大的吸收特征。 研究小组将通过在甲烷带的波长和相邻波长的波长下进行成像来进行大区域红外调查，以查找T-Dwarfs。 在甲烷带中微弱的物体可能是T-Dwarf恒星。研究活动将通过在研究工作中参与研究而产生更广泛的教育影响。 学生将在旧金山州立大学和犹他州谷州立学院（现为犹他州谷大学）招募，并将有机会参观合作中的另一家机构。 检测大量的T型紫外线将有助于改善恒星形成的理论，尤其是在最小质量的恒星和最大的行星之间的域中。
