The process of evolution of stars in our Universe has been interpreted

(a)   by matching theoretical models to the collective properties such as luminosity, temperature and size of millions of stars as we see them.
(b)   by matching theoretical models to the detailed observation of a few stars as they change in luminosity, temperature and size during their evolution.
(c)   by designing theoretical models solely on the basis of the known properties of matter, without reference to observational data on real stars, since we do not have a sufficiently long time base for stellar observations.
