Analytical theory for the initial mass function: II. Properties of the flow (2009)

Hennebelle, Patrick, Chabrier, Gilles

Recently, Hennebelle and Chabrier (2008) derived an analytical theory for the mass spectrum of non self-gravitating clumps associated with overdensities in molecular clouds and for the initial mass...

Bridging the Gap Between Stars and Planets: The Formation and Early Evolution of Brown Dwarfs (2009)

Mohanty, Subhanjoy, Burgasser, Adam, Chabrier, Gilles, Padoan, Paolo, Hennebelle, Patrick, Pascucci, Ilaria, ...

This White Paper, submitted to the National Academy of Sciences' Astro2010 Decadal Review Committee, focuses on 2 central themes in the study of young brown dwarfs -- their formation mechanism and...

The early stages of molecular cloud evolution in the magnetised interstellar medium: clump morphology and evolution (2008)

Banerjee, Robi, Vazquez-Semadeni, Enrique, Hennebelle, Patrick, Klessen, Ralf

We study the properties of clumps formed in three-dimensional simulations of converging flows in the magnetised, thermally bistable, warm neutral medium (WNM). Based on these simulations we find: (1)...

Our Knowledge of High-Mass Star Formation at the Dawn of Herschel (2008)

Motte, Frédérique, Hennebelle, Patrick

We review the theories and observations of high-mass star formation emphasizing the differences with those of low-mass star formation. We hereafter describe the progress expected to be achieved with...

Analytical theory for the initial mass function: CO clumps and prestellar cores (2008)

Hennebelle, Patrick, Chabrier, Gilles

We derive an analytical theory of the prestellar core initial mass function based on an extension of the Press-Schechter statistical formalism. With the same formalism, we also obtain the mass...

Protostellar collapse: A comparison between SPH and AMR calculations (2008)

Commercon, Benoit, Hennebelle, Patrick, Audit, Edouard, Chabrier, Gilles, Teyssier, Romain

The development of parallel supercomputers allows today the detailed study of the collapse and the fragmentation of prestellar cores with increasingly accurate numerical simulations. Thanks to the...

OUR KNOWLEDGE OF HIGH-MASS STAR FORMATION AT THE DAWN OF HERSCHEL (2007)

Motte, Frédérique, Hennebelle, Patrick

We review the theories and observations of high-mass star formation emphasizing the differences with those of low-mass star formation. We hereafter describe the progress expected to be achieved with...

Submillimeter Studies of Prestellar Cores and Protostars: Probing the Initial Conditions for Protostellar Collapse (2005)

Andre, Philippe, Bouwman, Jeroen, Belloche, Arnaud, Hennebelle, Patrick

Improving our understanding of the initial conditions and earliest stages of protostellar collapse is crucial to gain insight into the origin of stellar masses, multiple systems, and protoplanetary...

Detailed Studies of Cloud Cores: Probing the Initial Conditions for Protostellar Collapse (2003)

Andre, Philippe, Belloche, Arnaud, Hennebelle, Patrick, Ward-Thompson, Derek

Improving our understanding of the earliest stages of star formation is crucial to gain insight into the origin of stellar masses, multiple systems, and protoplanetary disks. We discuss recent...

Radio-millimetre investigation of galactic infrared dark clouds (2001)

Teyssier, David, Hennebelle, Patrick, Perault, Michel

This paper presents follow-up observations of the mid-Infrared dark clouds selected from the ISOGAL inner Galaxy sample. On-the-fly maps of 13CO, C18O and the 1.2 mm continuum emission have been...

Exact solutions of the aspherical axisymmetric gravo-magnetic condensation (2001)

Hennebelle, Patrick

We find exact and explicit solutions of the axisymmetric MHD equations of a self-gravitating polytropic gas. These solutions are able to describe a flat (uniform density) subsonic internal core,...
