The Process of Evolution of Stars in the Universe Has

question 84

Multiple Choice

The process of evolution of stars in the universe has been interpreted by

• A) matching theoretical models to the properties of similar stars at different distances from Earth, since more distant stars from an earlier time are observed, when the light left them.
• B) matching theoretical models to the collective properties, such as luminosity, temperature, and size, of millions of stars as observed.
• C) designing theoretical models solely on the basis of the known properties of matter, without reference to observational data on real stars, since there is not have a sufficiently long time base for stellar observations.
• D) matching theoretical models to the detailed observation of a few stars as astronomers watch them change in luminosity, temperature, and size during their evolution.
