Diffuse Nebulae, Wind-Blown Shells, and Planetaries

  • Lawrence H. Aller
Part of the Astrophysics and Space Science Library book series (ASSL, volume 112)


In preceding chapters we have reviewed physical processes associated with thermal excitation of spectra of various types of gaseous nebulae, H II regions, planetaries and supernova remnants. We must now examine more carefully some of the distinctive characteristics of these objects. We consider first certain of the classical diffuse galactic nebulae, properties of shells blown by stellar winds, and finally basic statistics, structures, and internal kinematics of planetary nebulae. In Chapter 12 we return to these latter objects in the context of stellar evolution; here we shall be concerned with some fundamental empirical data.
