Distance to the galactic centre 来自 国家科技图书文献中心 喜欢 0 阅读量: 20 作者:Surdin,V. G.摘要: This is a short review of the modern determination of the galactocentric distance R0 and some new results on the derivation of the value of R0 due to the metallicity distribution of ...
The OB stars are concentrated near the Galactic plane and should permit a determination of the distance to the Galactic center. van Leeuwen's new reduction of the Hipparcos catalog provides, after 824 Gould belt stars have been excluded, 6288 OB stars out to 1 kpc and Westin's compilation an...
This confirms the presence of a faint Outer arm toward l = 135 degrees. We also measured the full space motion of the object and find a large peculiar motion of ~20 km/s toward the Galactic center. This peculiar motion explains the large error in the kinematic distance estimate. We also...

This confirms the presence of a faint Outer arm toward l = 135°. We also measured the full space motion of the object and find a large peculiar motion of ~20 km s–1 toward the Galactic center. This peculiar motion explains the large error in the kinematic distance estimate. We also ...
The Galactic Distance Scale: Globular Clusters A new compilation of distance data for the Galactic globular clusters is used to estimate the distance to the Galactic center, R O . Three different ways of using the space distribution of the clusters lead to R O = (8.5 卤 1.0) kpc. The.....

The average distance (G) of a finite graph G = (V , E) is the average of the distances over all unordered pairs of vertices. A minimum average distance spanning tree of G is a spanning tree of G with minimum average distance. Such a tree is sometimes referred to as a minimum routing...
