    • isochronal Uniform in time; of equal time; performed in equal times. Two pendulums which vibrate in the same time are isochronal; also, the vibrations of a pendulum in the curve of a cycloid have the same property, being all performed in the same time, whether the arc be large or small. Also isochronous.

Hyperhamiltonian dynamics
Positioning a star or a family of stars in the HR diagram is fundamental to understand the structure and evolution of stars since it enables proper comparison with evolutionary tracks and computed isochrones.
