AST-0607644INSTITUTION: University of WashingtonPI: Suzanne HawleyCo-PI: Ian N ReidTITLE: Low Mass Stellar Luminosity and Mass FunctionsABSTRACTDr. Suzanne Hawley at the University of Washington, and Dr. Ian N. Reid, at the Space Telescope Science Institute, will undertake a project to determine the luminosity and mass functions for low-mass stars. To accomplish this goal, photometry from several modern, large-scale surveys will be combined to produce the largest of combined optical and infrared photometry for low-mass stars (~3 million stars). The sample will allow for an investigation of the luminosity and mass functions with as of now unattained statistical significance. The purpose of the study is to place constraints on star formation processes, the star formation history and the initial mass function in the disk of the Galaxy, Galactic formation and evolution, and the mass to light ratio of external galaxies.This work will form the core component of a PhD thesis. Additionally, new software tools will be developed that are applicable to the National Virtual Observatory (NVO), and they will be made freely available. An exercise on galactic structure and star counts, as well as simulated fly-by's of the ~3 million stars in the sample, will be incorporated into the general undergraduate teaching curriculum at the University of Washington (UW). Finally, research projects and summer support will be provided for students in a program designed for entering UW freshmen who are interested in math and science, and who are traditionally underrepresented in astronomy.

AST-0607644机构：华盛顿大学PI：Suzanne Hawley Co-PI：Ian N Reid标题：低质量恒星光度和质量函数。华盛顿大学的苏珊娜·霍利和伊恩·N·哈勒博士。里德在太空望远镜科学研究所，将承担一个项目，以确定低质量恒星的光度和质量函数。 为了实现这一目标，将结合几个现代大规模调查的测光，以产生最大的低质量恒星（约300万颗恒星）的组合光学和红外测光。该样本将允许调查的光度和质量的功能与目前尚未达到的统计意义。 本研究的目的是对星星的形成过程、星星的形成历史和星系盘中的初始质量函数、星系的形成和演化以及外部星系的质光比进行约束，这项工作将构成博士论文的核心部分。此外，还将开发适用于国家虚拟天文台的新软件工具，并将免费提供。关于星系结构和星星计数的练习，以及样本中约300万颗恒星的模拟飞越，将被纳入华盛顿大学（UW）的普通本科教学课程。 最后，研究项目和夏季支持将提供给学生在一个计划，旨在进入华盛顿大学新生谁感兴趣的数学和科学，谁是传统上在天文学代表性不足。
