The efficiency per free-fall time as a ratio of the Star Formation Rate to the gas-infall rate in collapsing cores: dependence on the core definition, accretion, and radial structure
Fabián Quesada-Zúñiga, Manuel Zamora-Avilés, Enrique Vázquez-Semadeni +3
A parameter used to characterise star formation activity in MCs is the efficiency per free-fall time, , although commonly referred to as an efficiency, it is formally t…

Comparing the Relation inside a Giant Molecular Cloud
Carlos G. Román-Zúñiga, Aina Palau, Javier Ballesteros-Paredes +3
In this paper we present a simple analysis around scaling relations derived from the Schmidt conjecture for star-forming molecular clouds, at the intra-cloud scale. Using a hierarc…

Synthetic polarization observations of magnetized pillars in HII regions: Assessing the reliability of the Davis-Chandrasekhar-Fermi method
Luis Andrés Hernández-Cruz, Manuel Zamora-Avilés, Abraham Luna +6
We investigated the morphology and strength of magnetic fields in pillar-shaped structures at the boundaries of HII regions by combining three-dimensional radiation-magnetohydrodyn…
