Vol 1 (pub in , 2nd ed) titled "Double Stars" covers double and multiple star systems; more intensive coverage has been given to micrometers and micrometric measures.

Stobbe; Practical Astronomy, by Jason John Nassau; The Universe in the Light of Modern Physics, by Max Plank; Publications of the Yerkes Observatory, Vol. VI: Micrometric Measures of Star Clusters. Star clusters provide us with a lot of information that is relevant to the study of stars in general. The main reason is that we assume that all stars in a cluster formed almost simultaneously from the same cloud of interstellar gas, which means that the stars in the cluster .

THE STELLAR CLUSTER χ PERSEI.—Mr.O. A. L. Pihl has completed a micrometric examination, begun in , of the group χ of the great star cluster in Perseus, and the results are published by. Globular Clusters. Globular clusters were given this name because they are nearly symmetrical round systems of, typically, hundreds of thousands of stars. The most massive globular cluster in our own Galaxy is Omega Centauri, which is ab light-years away and contains several million stars (Figure ).Note that the brightest stars in this cluster.   All chapters have been rewritten and, in most cases, extended. More intensive coverage has been given to micrometers and micrometric measures. The Catalogue section has been enlarged by more than sets of measures. One hundred forty-three additional double and multiple star Reviews: 1. Milky Way Galaxy Distances Measures for Open Star Clusters. An attraction of open star clusters is that their distances from the Sun, and therefore the distances to hundreds of stars of the same heritage, can be derived through methods other than the measurement of annual star clusters .

Finding a star map in the book, Barnard was. able to learn the conventional names of the objects with which he was already so familiar. In January, , still employed Micrometric Measures of Star Clusters. We find cluster radii between and ~10 pc, and one exceptionally large cluster candidate with a radius of pc. The median radius is pc. We find 70 clusters in our sample which have colours consistent with being old GC candidates and we find 6 new "faint fuzzy" clusters .   Observations made with the GMT at Melbourne also included stars: double stars and star systems, clusters of stars, searches for companions of stars, measurements of double stars, . 疏散星團,也稱為銀河星團,是由同一個巨分子雲中的數百顆至數千顆恆星形成的集團。 在銀河系中發現的疏散星團已經超過1,個,並且被認為還存在更多 。 它們環繞著銀河中心運轉時,只靠著微弱的 .
