CAREER: Stellar Populations in the Local Volume

萨拉赫迪尼博士将对银河系附近星系的恒星群进行研究，研究范围约为5Mpc，目的是了解具有一系列形态类型的星系的恒星形成和化学演化史。我们将特别关注这些星系中动力相互作用、恒星形成和化学富集物之间的相互作用。一些研究领域的工作将提供观测数据，以研究环境对星系形成和演化的影响。他的研究计划包括研究银河系和附近的麦哲伦星云中的星系团，以开发覆盖一系列金属丰度和年龄的颜色-星等图的网格。这些将被用作基准，据此可以确定矮小星系的恒星数量。他还将通过研究射手座矮星和麦哲伦云的局部例子来研究动力学相互作用对恒星形成的影响。他还计划使用各种数据来比较和对比银河系、M33和M31的恒星数量。随着更大、更有效的望远镜的出现，这些技术和类型的观测将进一步扩展到当地团体内部和之外。他还将在未来5年开展一系列教育和外展活动，从到当地K-12教室的外展和盖恩斯维尔地区的公开讲座，到设计新的本科课程。他的研究计划自然包括让本科生和研究生有机会高度参与并做出重要贡献。

Dr. Sarajedini will carry out a study of the stellar populations of galaxies in the local neighborhood of the Milky Way out to about 5 Mpc, with the aim of understanding the star formation and chemical evolutionary histories of galaxies with a range of morphological types. Particular attention will be paid to the interplay of dynamical interactions, star formation, and chemical enrichment in these galaxies. Work in a number of research areas will provide observational data to study the effects of environment on galaxy formation and evolution. His research plan includes studies of clusters in the galaxy and nearby Magellanic Clouds to develop a grid of color-magnitude diagrams that cover a range of metallicity and age. These will be used as fiducials against which the stellar populations of dwarf galaxies can be determined. He will also investigate the effects of dynamical interactions on star formation by studying the local examples of the Sagittarius dwarf and the Magellanic Clouds. He also plans to compare and contrast the stellar populations in the Milky Way, M33, and M31 using a variety of data. As larger and more efficient telescopes become available, these techniques and types of observations will be extended further into and beyond the local group. He will also carry out a suite of educational and outreach activities over the next 5 years, which range from outreach to local K-12 classrooms and public talks for the Gainesville area, to designing a new undergraduate course. His research program naturally includes opportunity for undergraduates and graduate students to be highly involved and significant contributors.
