520.3.#.a: In this paper we study the gravitational collapse of a molecular hydrogen gas cloud composed of a core plus a gas envelope surrounding the core. We numerically simulate the collapse of four cloud models to take a glimpse to the time evolution of several dynamic variables, such as the angular momentum and the aem ratio, as well as the ratios between the thermal and rotational energies with respect to the potential gravitational energy, denoted as α and β, respectively, among others. We re-take those models introduced by Arreaga et al. (2010) in the present paper in order to produce different outcomes of the collapsing cloud characterized in terms of the aforementioned dynamical variables. Such characterization was missing in the paper by Arreaga et al. (2010), and here we show that the gas envelope extension effects on the collapsing core can be quantitatively compared.In this paper we study the gravitational collapse of a molecular hydrogen gas cloud composed of a core plus a gas envelope surrounding the core.

Resumen
In this paper we study the gravitational collapse of a molecular hydrogen gas cloud composed of a core plus a gas envelope surrounding the core. We numerically simulate the collapse of four cloud models to take a glimpse to the time evolution of several dynamic variables, such as the angular momentum and the aem ratio, as well as the ratios between the thermal and rotational energies with respect to the potential gravitational energy, denoted as α and β, respectively, among others. We re-take those models introduced by Arreaga et al. (2010) in the present paper in order to produce different outcomes of the collapsing cloud characterized in terms of the aforementioned dynamical variables. Such characterization was missing in the paper by Arreaga et al. (2010), and here we show that the gas envelope extension effects on the collapsing core can be quantitatively compared.In this paper we study the gravitational collapse of a molecular hydrogen gas cloud composed of a core plus a gas envelope surrounding the core.
