Hub-filament systems and the growth of massive stars: episodic accretion, clustered environments, and projection effects
Dana Makarova, Dana Alina, Paolo Padoan +4
The processes controlling the early mass growth of future massive stars remain poorly understood, particularly the connection of this growth to star clustering and hub-filament sys…
Random gas motions inside sub-parsec scale supercritical filaments
Chao Zhang, Tie Liu, Mika Juvela +12
Supercritical gas filaments in molecular clouds host the dense cores in which new stars form. The mechanisms governing their formation and subsequent gas accretion remain poorly un…
Compact HII Regions as Clocks of Massive-Star Formation: Evidence for Long Formation Timescales
Paolo Padoan, Mark Gieles
We revisit the luminosity function (LF) of compact HII regions in the context of the inertial--inflow model (IIM), in which massive stars assemble over extended, mass-dependent tim…
Globular cluster formation from inertial inflows: accreting extremely massive stars as the origin of abundance anomalies
Mark Gieles, Paolo Padoan, Corinne Charbonnel +2
We use the inertial-inflow model of massive star formation to describe the formation of globular clusters (GCs) in turbulent molecular clouds. A key aspect of this model is that th…
The Formation of Protoplanetary Disks through Pre-Main Sequence Bondi-Hoyle Accretion
Paolo Padoan, Liubin Pan, Veli-Matti Pelkonen +2
Protoplanetary disks are traditionally described as finite mass reservoirs left over by the gravitational collapse of the protostellar core, a view that strongly constrains both di…
Origin and Evolution of Angular Momentum of Class II Disks
Veli-Matti Pelkonen, Paolo Padoan, Mika Juvela +2
Context: While class II pre-main-sequence (PMS) stars have already accreted most of their mass, the continued inflow of fresh material via Bondi-Hoyle accretion acts as an addition…
