[M5 CMD (Fig 4)]

Plotting a relation between visual magnitude (V) and color index (B-V) for individual stars of the cluster M 5, one obtains this picture of an old, distorted apple-tree with only two branches. It is, nevertheless, the Tree of Knowledge for astrophysicists.
(A): Main Sequence.
(B): Red Giant Branch.
(C): Helium flash occurs here
(D): Horizontal Branch (HB)
(E): Schwarzschild space in the HB
(F): White Dwarfs (below the arrow).
