Description acceptable. This process begins when exceeding a limit proportional to the fourth power of the speed of sound over alpha times big-G to the three-halves. (10[1])Edwin Salpeter’s IMF (-5[1])models the results of this process. (10[1])Recent estimates (10[1])suggest that the rate of this process scales with the 1.4th power of the surface gas density by the empirical Kennicutt–Schmidt law. Exceeding the (10[1])Bonnor–Ebert and Jeans masses will begin this process, (10[2])which produces (10[2])T (10[2])Tauri (10[1])objects (10[1]-5[1])that (10[1])then evolve to follow (10[1])the Hayashi (10[2])track (10[1])downwards. (10[3]-5[3])This process (10[1])begins when a molecular (10[1])cloud in the ISM (10[5])loses (10[2])hydrostatic equilibrium (10[3]-5[1])and undergoes (10[2])gravitational collapse (10[3]-5[2])so that fusion occurs. (10[3]-5[1])For 10 points, (10[3])identify this process that creates (10[1])the objects found (10[1])on Hertzsprung–Russell (10[1])diagrams, (10[2])such as Alpha Centauri. (10[1])■END■ (10[11]0[1])
