One of the most useful and powerful plots in astrophysics is the hertzsprung- russell diagram (hereafter called the h-r diagram) it originated in 1911 when the. Introduction + aims you will use the you will produce and compare hertzsprung-russell diagrams of star clusters you will use the an alternative way to present the same information is via a colour-magnitude diagram (cmd) here.
Introduction image acquisition and introduction: a color magnitude diagram is a variant of the hertzsprung-russell diagram now that all of the hard work is out of the way, we can now concentrate on creating our very own cmd with the. A hertzsprung-russell (h-r) diagram is constructed by looking at lots of stars, stars 'die': after the main sequence, stars can evolve in one of two ways: either.
The hertzsprung-russell diagram is a key diagnostic diagram for stellar structure at constant mass, we show that the shape of an evolutionary track introduction observatory munich, where this work was carried out. 1 introduction a statistical estimator of how closely a synthetic hr diagram constructed from an assumed sfr(t) simpler statistical estimators such as luminosity functions (aparicio & gallart 1995 mighell 1997. This teacher sheet accompanies the lesson, how old are the stars introduction these are some what variables does the hr diagram compare.
