This gigantic data set allows building the largest, deepest, and most accurate color-magnitude diagram ever produced, containing more than ten times more stars than any previous study.

The problem of course is that the colour magnitude diagram is complex and many-valued. So a star with a given colour could belong to one of several different stellar populations with different ...

The colour–magnitude diagram of NGC 1651 exhibits a clearly extended main-sequence turn-off ... (for example on the red side of the main sequence).

They must therefore have very large radii. They are located in the giant sequence. The color-magnitude diagram (CMD) is equivalent in practice to the Hertzsprung-Russell diagram (HRD). The spectral ...
