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.

AST-0607312机构：德克萨斯大学奥斯汀分校PI：John Lacy合作PI：丹尼尔贾菲标题：双子座星星形成区域的高分辨率中红外光谱。得克萨斯大学奥斯汀分校的约翰·莱西和丹尼尔·贾菲博士将与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，以及超致密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，并将其扩展到较低质量的物体。 此外，利用双子望远镜上TEXES的灵敏度，将测量谱线的多普勒轮廓，提供关于恒星盘中分子和温度随半径分布的信息。 最后，双子座更高的空间分辨率将允许对遥远的超紧凑HII区域进行研究。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观测将产生更广泛的影响。
