Inverse Hubble Flows in Molecular Clouds
Jesús A. Toalá, Enrique Vázquez-Semadeni, Pedro Colín +1
Motivated by recent numerical simulations of molecular cloud (MC)evolution, in which the clouds engage in global gravitational contraction, and local collapse events culminate sign…
The Free-Fall time of finite Sheets and Filaments
Jesús A. Toalá, Enrique Vázquez-Semadeni, Gilberto C. Gómez
Molecular clouds often exhibit filamentary or sheet-like shapes. We compute the free-fall time ($\tff$) for finite, uniform, self-gravitating circular sheets and filamentary clouds…
Competitive Accretion in Sheet Geometry and the Stellar IMF
Wen-hsin Hsu, Lee Hartmann, Fabian Heitsch +1
We report a set of numerical experiments aimed at addressing the applicability of competitive accretion to explain the high-mass end of the stellar initial mass function in a sheet…
