High Resolution Mid-Infrared Spectroscopy of Star Formation Regions on Gemini

机构：德克萨斯大学奥斯汀分校，pi: John LacyCo-PI: Daniel JaffeTITLE：双子座恒星形成区的高分辨率中红外光谱研究德克萨斯大学奥斯汀分校的John Lacy和Daniel Jaffe博士将与TEXES的仪器团队一起进行观测项目。该计划包括研究恒星形成区域的分子气体，原行星盘中的分子，以及超紧凑H II区域的电离气体。TEXES观测到的分子是研究颗粒地幔化学和蒸发作用的良好探针。该小组将继续研究大质量年轻恒星周围气体的化学和物理条件，并将其扩展到低质量天体。此外，利用双子座望远镜上的TEXES的灵敏度，将测量谱线的多普勒谱线，提供分子分布和恒星盘半径温度的信息。最后，双子座更大的空间分辨率将允许研究遥远的超紧凑HII区域。包括两名研究生在内的TEXES科学家将支持天文学界成员使用TEXES进行观测。K-12教师前往夏威夷参加TEXES观察将产生更广泛的影响。

AST-0607312INSTITUTION: University of Texas at AustinPI: John LacyCo-PI: Daniel JaffeTITLE: High Resolution Mid-Infrared Spectroscopy of Star Formation Regions on Gemini ABSTRACTDr. John Lacy and Dr. Daniel Jaffe, at the University of Texas at Austin, will undertake observational projects with the TEXES" instrument team. The program includes studies of molecular gas in star-formation regions, molecules in protoplanetary disks, and ionized gas in ultracompact H II regions. The molecules observed by TEXES are good probes of the effects of grain mantle chemistry and evaporation. The study of the chemical and physical conditions in the gas around massive young stars will be continued by the group, and extended to lower mass objects. Also, with the sensitivity of TEXES on the Gemini telescope, Doppler profiles of lines will be measured, providing information on the distribution of molecules and temperature with radius in stellar disks. Finally, the greater spatial resolution of Gemini will allow for the study of distant Ultracompact HII regions.TEXES scientists, including two graduate students, will support observations with TEXES by members of the astronomical community. An additional broader impact will result from K-12 teachers traveling to Hawaii to participate in TEXES observations.
