The Impact of Massive Stars on the Evolution of Nearby Galaxies

不规则星系是宇宙中最常见的星系类型，在它们演化的所有方面中，没有一个比最大质量恒星的影响更重要。 通过异常强烈的恒星风和随后的超新星爆炸，大质量恒星存款巨大的能量进入它们的环境，引发新一代恒星的形成，分散新形成的化学元素，并推动宿主星系的演化。 该项目的重点是大质量恒星与其环境之间的这种动态和经常暴力的关系。利用国家射电天文台的超大阵列和WIYN（威斯康星-印第安纳-耶鲁-国家天文台）光学望远镜上的新光纤技术，参与者将测量恒星对其环境的影响，并测量单个星系减轻这些大质量恒星影响的能力。 这项系统的研究将揭开不规则星系如何随着时间的推移而演变的奥秘，以及它们今天如何继续演变。***

AST 0098438WilcotsIrregular galaxies are the most common types of galaxy in the Universe and of all the facets of their evolution, none is more important than the influence of the most massive stars. Through exceptionally strong winds and subsequent explosions as supernovae, massive stars deposit tremendous amounts of energy into their environments, triggering the formation of new generations of stars, dispersing newly formed chemical elements, and driving the evolution of the host galaxy. This project focuses on this dynamic and often violent relationship between massive stars and their environments. Using a combination of the National Radio Astronomy Observatory's Very Large Array and the new fiber-optic technology on the WIYN (Wisconsin-Indiana-Yale-National Observatories) optical telescope, the participants will measure the impact of stars on their environment and measure the ability of an individual galaxy to mitigate the effects of these massive stars. This systematic investigation will unravel the mysteries of how irregular galaxies have evolved over time, and how they continue to evolve today. ***
