Features

  • Offers a fundamental introduction to astronomy, astrophysics, and cosmology
  • Covers stellar atmospheres, structure, and energy sources
  • Takes a detailed look at white dwarf and neutronstars
  • Requires a basic understanding of physics and mathematics, but assumes no prior knowledge of astronomy
  • Includes extensive references to information at more advanced levels

    • Summary

    Designed for students who have a basic understanding of physics and mathematics, this text provides a fundamental, three-in-one introduction to astronomy, astrophysics, and cosmology. The astronomy section explores fundamental topics such as the celestial coordinate system, stellar classification schemes, H-R diagrams, and the masses and radii of stars. The astrophysics section addresses stellar structure, stellar atmospheres, energy generation in stars, and nucleosynthesis. Also covering galactic structure and rotation, the cosmology section introduces the Robertson-Walker metric and Friedman models of the universe and discusses the present status of the Hubble constant along with problems associated with the age of the universe.

    Numerous problems, diagrams, and up-to-date references make this an ideal introductory text for graduate courses in physics, mathematics, space physics, or any program for which astronomy is an option.
