Journal Article
Annual review of astronomy and astrophysics, ISSN 1545-4282, 08/2010, Volume 48, Issue 1, pp. 581 - 629
The age of an individual star cannot be measured, only estimated through mostly model-dependent or empirical methods, and no single method works well for a broad range of stellar types or for a full range in age...
