Molecular Evolution in Collapsing Prestellar Cores. III. Contraction of a Bonnor‐Ebert Sphere
The gravitational collapse of a spherical cloud core is investigated by numerical calculations. The initial conditions of the core lie close to the critical Bonnor-Ebert sphere with a central density of ~104 cm-3 in one model (α = 1.1), while gravity overwhelms pressure in the other (α = 4.0), where …
