CAREER: Stellar Populations in the Local Volume

塞拉耶迪尼博士将对银河系附近的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历史。我们将特别关注这些星系中动力学相互作用、恒星形成和化学富集的相互作用。许多研究领域的工作将为研究环境对星系形成和演化的影响提供观测数据。他的研究计划包括研究银河系中的星团和附近的麦哲伦星云，以开发一个覆盖金属丰度和年龄范围的彩色星等图网格。这些数据将被用作确定矮星系恒星数量的基准。他还将通过研究当地的人马座矮星系和麦哲伦星云的例子来研究动态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中的恒星数量。随着更大、更高效的望远镜变得可用，这些技术和观测类型将进一步扩展到本地群体之外。他还将在未来5年内开展一系列教育和推广活动，范围从推广到当地的K-12教室和盖恩斯维尔地区的公开演讲，到设计一门新的本科课程。他的研究项目自然为本科生和研究生提供了高度参与和做出重大贡献的机会。

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.
