There are three wel1-defihed classes
OF stars, judged by the quality of light
they yield. In the first class are the
clear. white and blush white stars like
Sirius and Vega. These are supposed to
be the hottest stars and the most lumin-
Gus in proportion to the extent of their
surface. Then there are the golden
yellow or pale orange stars, of which
Arcturus and Capella are fine examples.
These have begun to cool. Finally, we
have the deep orange and red stars, like
Aldebarah and Antares. These have
advanced still further in the cooling
process. -"l ' ''''''''- 7+is-'''
