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…
ALMAGAL VIII. Early phases of triggered star formation in source AG286.07161.8229
C. Mininni, S. Molinari, W. J. Kim +50
Several theoretical and observational studies have shown that new waves of triggered star-formation can be induced by the feedback from newly formed massive protostars, due to the…
Does supernova feedback regulate the star formation rate in dwarf galaxies?
D. Whitworth, E. Vázquez-Semadeni, J. Ballesteros-Paredes +1
Stars form in cold, dense clouds embedded in galactic discs, but whether their formation is primarily regulated by gravitational collapse, turbulence, or stellar feedback remains u…
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, Luis Andrés Hernández-Cruz, Manuel Zamora-Avilés +11
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…
Pressure Regulated Formation of Molecular Clouds and Stars: The case of the Milky Way
José Franco, Aldo RodrÃguez-Puebla, Javier Ballesteros-Paredes +1
We present a steady-state analytical model for pressure-regulated formation of molecular clouds (MC) and stars (SF) in gaseous galactic disks and apply it to the Milky Way (MW). MC…
