These objects are commonly studied using a log T-log rho graph, from which one can easily find if gas pressure or radiation pressure is more important.
These objects are commonly studied using a log T-log rho graph, from which one can easily find if gas pressure or radiation pressure is more important. The opacity of these objects is proportional to density times temperature to the negative seven-halves according to Kramers's law. A condition for the formation of these things is the Jeans length being exceeded by a molecular cloud, which will (*) collapse and tend to form "clusters" of them. These objects are classified according to their spectral lines in the Harvard classification scheme, which divides them - in order of decreasing temperature - into the categories O, B, A, F, G, K or M. For 10 points, name these astronomical objects whose life cycles are depicted on H-R diagrams, and which include red giants and brown dwarfs.
