Exploring the Solar Neighborhood with the GALEX All Sky Survey

我们银河系中元素创造的历史保存在矮星中。 通过在紫外线（UV）波长下观察附近的恒星，研究人员将揭开这段历史。研究人员将使用GALEX卫星图像来测量太阳附近相对暗淡的矮星的属性。 这些观测是在紫外波长下进行的，补充了地面望远镜在光学和红外波长下进行的观测。 研究人员还将推进我们对附近恒星的了解，并对其他天文学领域产生潜在影响。 该研究活动旨在帮助培养一名年轻的科学家，该项目被定义为一套适合高中生的项目。研究人员的团队将把代表性不足的少数民族纳入他们的研究，扩大对基础科学的参与。研究人员将测量恒星的紫外线颜色，并校准颜色，以估计恒星的金属丰度和恒星年龄。他们的研究将有助于了解我们银河系中恒星的形成和年龄。 他们将联合收割机结合以前光学巡天（如斯隆数字巡天和日内瓦-哥本哈根巡天）对矮星星颜色的测量，以确定银河系恒星的年龄-金属丰度关系和年龄-轨道关系。

The history of element creation in our Milky Way galaxy is preserved in dwarf stars. By observing the nearby stars at ultraviolet (UV) wavelengths the investigators will unravel that history. The investigators will use the GALEX satellite images to measure the properties of the relatively faint dwarf stars in the solar neighborhood. These observations, made at UV wavelengths, complement observations made at the optical and infrared wavelengths with ground based telescopes. The investigators will also advance our knowledge of nearby stars, with potential impacts across other fields of astronomy. The research activity is designed to help train a young scientist and the project is defined as a set of projects suitable for high school students. The investigator's team will bring underrepresented minorities into their research, expanding participation in basic science.The investigators will measure the UV-based colors of stars and calibrate the colors to estimate stellar metallicity and stellar age. Their research will aid in understanding the formation and age of stars in our galaxy. They will combine measurements of dwarf star colors from previous optical surveys, such as the Sloan Digital Sky Survey and the Geneva-Copenhagen Survey, to determine the age-metallicity relations and age-versus-trajectory for stars in the Milky Way.
