Stellar structure
-
energy transport
radiation
allows energy produced by nuclear reactions and gravitation to be carried to the surface via photons
-
path used by photons called " drunken sailor problem" bcs the path followed by the absorbed and re-emitted photons like that followed by someone too inebriated to stand up for long
in massive stars; the dominant method of cooling or stars in advanced burning stages and also plays a central role in events like supernovae associated with the death of massive stars.
convection
-
a very efficient method of energy transport because it involves the vertical motion of large packets of gas.
-
conduction
-
-
under certain conditions involving very high densities the matter of a star may become what is termed "degenerate"
not important in normal stars, but must also be accounted for if stars contain degenerate matter.
stars clusters
= group of stars that formed out of the same molecular cloud, and which remains bound together by the mutual gravitational attraction of its components
open clusters
-
-
sometimes called GALACTIC cluster due to their location on the dusty spiral arms on the plane of spiral galaxies.
-
-
as the cluster rotates around the galaxy it eventually disperses due to gravitational perturbations with other objects in the galaxy
-
-
globular clusters
contain several thousand to one million stars in spherical, gravitationally-bound system.
-
-
-
prominent examples include 47 TUC, M4 and OMEGA CENTAURI
