A mass invariant in a compressible turbulent medium
Pierre Dumond, Jérémy Fensch, Gilles Chabrier +1
Predicting the measurable statistical properties of density fluctuations in a supersonic compressible turbulent flow is a major challenge in physics. In 1951, Chandrasekhar derived…

Do tides play a role in the determination of the pre-stellar core mass function?
Pierre Dumond, Gilles Chabrier
Recent studies have examined the role of tides in the star formation process. They suggest, notably, that the tides determine the characteristic mass of the stellar initial mass fu…

Impact of the shape of the prestellar density fluctuations on the core mass function
Pierre Dumond, Gilles Chabrier
It is well known that departure from sphericity in the geometry of primordial dark matter halos modifies their mass function. The ellipsoidal collapse model yields a better agreeme…
