In the text descriptions of the individual objects, you will often find the indication of a type class for both the open and the globular clusters. |
 |
|
|||||||||||||||
Open star clusters are mostly classified according to a scheme developed by Robert Trumpler in 1930. There are three indications for this. The Roman numerals from I to IV indicate the concentration and separation from the surrounding star field (from strongly to weakly concentrated).
The Arabic numerals from 1 to 3 indicate how much each star varies in brightness (from low to strong). The letters p, m, or r indicate whether the cluster has few (poor), average (medium), or many (rich) stars.
In addition, three further criteria can be given: n (nebulosity) means that interstellar, luminous matter clouds are embedded in the cluster; e (elongated) means that the cluster appears to be spread out in one direction; and u (unsymmetrical) means that the stars in the cluster are scattered in different directions.
Globular clusters:
Globular clusters are classified by their apparent concentration according to an Ssystem developed by Harlow Shapley and his graduate student Helen Sawyer Hogg beginning in 1927. The scale ranges from Roman I to XII, with Class I representing strong concentration and Class XII representing the weakest concentration.
