Galactic Structure and Kinematics from Absolute Proper Motions

AST-9530632 从绝对自行看银河系的结构和动能。 位于圣克鲁斯的加州大学的琼斯博士和同事们将把从北方自行巡天（NPM）得出的绝对自行应用于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系自转的权威性研究，对远离银道面的恒星数量变化和运动学的强有力探测，对RR天琴座光度和运动学的大量研究，以及对岁差修正的天体测量研究，以及NPM与其他目录的比较。 这些研究人员还将开始对NPM调查向银河系低纬度地区的扩展进行观测。 =================================================

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. =================================================
