Galactic Structure and Kinematics from Absolute Proper Motions

AST-9530632 绝对自行的银河结构和运动学。 琼斯博士和加州大学圣克鲁斯分校的同事将把北方自行巡天 (NPM) 得出的绝对自行应用于解决星系结构和运动学中的突出问题。 其中包括对太阳运动和银河自转的明确研究，对远离银河平面的恒星数量和运动学变化的强大探测器，对天琴座RR光度和运动学的大规模研究，以及进动修正的天体测量研究以及NPM与其他星表的比较。 这些研究人员还将开始将 NPM 巡天扩展到低银河系纬度地区进行观测。 ===================================================

AST-9530632 Galactic Structure and Kinematics from Absolute Proper Motions. Dr. Jones and colleagues at the University of California at Santa Cruz will apply the absolute proper motions derived from the Northern Proper Motion Survey (NPM) to outstanding problems in galactic structure and kinematics. These include a definitive study of solar motion and galactic rotation, a powerful probe of changing stellar populations and kinematics away from the galactic plane, a massive study of RR Lyrae luminosities and kinematics, and astrometric studies of the corrections to precession and comparisons of NPM with other catalogs. These researchers will also begin observations on an extension to the NPM Survey toward low galactic latitudes. =================================================
