Slingshot mechanism in Orion: Kinematic evidence for ejection of protostars by filaments

Slingshot mechanism in Orion: Kinematic evidence for ejection of protostars by filaments

By comparing three constituents of Orion A (gas, protostars, and pre-main-sequence stars), both morphologically and kinematically, we derive the following conclusions. The gas surface density near the integral-shaped filament (ISF) is very well represented by a power law, Σ(b) = 37 M⊙ pc-2(b/pc)−5/8...

Zusammenfassung:By comparing three constituents of Orion A (gas, protostars, and pre-main-sequence stars), both morphologically and kinematically, we derive the following conclusions. The gas surface density near the integral-shaped filament (ISF) is very well represented by a power law, Σ(b) = 37 M⊙ pc-2(b/pc)−5/8, for the entire range to which we are sensitive, 0.05 pc
