Three dimensional views of the evolutionary stages of the stars.
Understanding the diagrams:
These 3D Hertzsprung-Russell diagrams introduces a third axis representing the age of the stars. The color coding of each point in the diagram corresponds to the evolutionary phase of the stars:
Protostars: Green
Main Sequence: Yellow
Red Giant Branch: Red
Sub Giants: Cyan
Horizontal Branch: Orange
Supergiants: Purple
Red Supergiants: Dark Red
Asymptotic Giant Branch: Very Dark Red
Post-AGB (Pre-White Dwarf) Brown
White Dwarves: White
Neutron Stars: Gray
Black Holes: Black
Tracing the life cycle of a star with 1 solar mass:
This diagram illustrates the journey of a star with 1 solar mass through its various life stages. Each point in this diagram marks a point in time in the star's evolution, from its early days as a protostar to its final stages as a white dwarf.
