CAREER: Stellar Populations in the Local Volume

Sarajedini博士将对银河系附近约5 Mpc的星系的恒星群进行研究，目的是了解具有一系列形态类型的星系的星星形成和化学演化历史。 将特别注意这些星系中动力学相互作用、星星形成和化学富集的相互作用。 在若干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中的星团和附近的麦哲伦云，以开发一个涵盖金属丰度和年龄范围的颜色星等图网格。 这些将被用来作为基准，对矮星系的恒星人口可以确定。 他还将通过研究人马座矮星和麦哲伦星云的本地例子，研究动力相互作用对星星形成的影响。 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。 随着更大和更有效的望远镜的出现，这些技术和观测类型将进一步扩展到本地组和超出本地组。 他还将在未来5年内开展一系列教育和推广活动，从推广到当地的K-12教室和盖恩斯维尔地区的公开讲座，到设计一门新的本科课程。 他的研究计划自然包括本科生和研究生的机会，高度参与和重大贡献者。

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.
