The slope of the power spectrum of the density field in isothermal supersonic compressible turbulence
Pierre Dumond, Jérémy Fensch, Gilles Chabrier +1
The power spectrum (PS) of the density field in supersonic turbulence is a fundamental quantity that characterizes the statistical properties of the structures formed in compressib…
Search for exocomets transits in Kepler light curves: Ten new transits identified
Pierre Dumond, Alain Lecavelier des Etangs, Flavien Kiefer +2
The Kepler mission, despite its conclusion over a decade ago, continues to offer a rich dataset for uncovering new astrophysical objects and phenomena. In this study, we conducted…
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…
The role of turbulence in setting the phase of the ISM and implications for the star formation rate
Tine Colman, Patrick Hennebelle, Noé Brucy +10
In this work, we explore the link between star formation, turbulence and the thermal state of the multi-phase ISM. We analyse a suite of stratified box simulations modelling a real…
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…
A consistent explanation for the unusual initial mass function and star formation rate in the Central Molecular Zone (CMZ)
Gilles Chabrier, Pierre Dumond
We examine various physical processes that may explain the shallow high-mass slope of the IMF as well as the low SFR in star-forming molecular clouds (MCs) in the Central Molecular…
