THE PHYSICS OF STARS AND THEIR ASTRONOMICAL IDENTIFICATION
Abstract
ABSTRACT
In this study of the
e physics of stars and their astronomical identification, it is
évident
I that stars
undergo certain physical processes as they live through their life
cycle. How gravity, magnetic field and nuclear fusion play a role in stelar
evolution is explained extensively. This research describes the structure and
evolution of stars. The structure and evolution of a star is determined by the laws
of Hydr'ostatic equilibrium, energy transport and generation and conservation of
energy while the mass of the star is the governing factor in the evolution and
structure of the star and determines its properties. Also, stellar spectra is discussed
in this work. Different elements absorb different wavelengths of light. The
Spectrum ofa star lets us know what elements are in the star. Finally, stars and
how they are identified astronomically is also discussed as different stars have
diferent astronomical identification. This paper uses established techniques in
cultural astronomy to identify seasonal stars in the traditions of the Kaurna
Aboriginal people of the Adelaide Plains, South Australia.
