The Interplay of Magnetic Fields, Fragmentation and Ionization Feedback in High-Mass Star Formation
Magnetic Fields Fragmentation High-Mass Star Formation
2011/1/13
Massive stars disproportionately influence their surroundings. How they form has only started to become clear recently through radiation gas dynamical simulations. However, until now, no simulation ha...
Non-convergence of the critical cooling timescale for fragmentation of self-gravitating discs
accretion accretion discs protoplanetary discs planets and satellites
2010/11/10
We carry out a resolution study on the fragmentation boundary of self-gravitating discs. We perform three-dimensional Smoothed Particle Hydrodynamics simulations of discs to determine whether the crit...
Is protostellar heating sufficient to halt fragmentation? A case study of the massive protocluster G8.68-0.37
stars formation — submillimeter — stars: winds outflows — ISM clouds — stars
2010/11/11
If star formation proceeds by thermal fragmentation and the subsequent gravitational collapse of the individual fragments, how is it possible to form fragments massive enough for O and B stars in a ty...
The Effects of Radiation Feedback on Early Fragmentation and Multiplicity
Radiation Feedback Early Fragmentation
2011/1/10
Forming stars emit a significant amount of radiation into their natal environment. While the importance of radiation feedback from high-mass stars is widely accepted, radiation has generally been igno...
The Formation of Low-Mass Binary Star Systems Via Turbulent Fragmentation
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
We characterize the infall rate onto protostellar systems forming in self-gravitating radiation-hydrodynamic simulations. Using two dimensionless parameters to determine disks' susceptability to gravi...
The fragmentation of expanding shells III: Oligarchic accretion and the mass spectrum of fragments
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
We use SPH simulations to investigate the gravitational fragmentation of expanding shells through the linear and non--linear regimes.
Stellar and substellar initial mass function: a model that implements gravoturbulent fragmentation and accretion
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2010/12/28
In this work, we derive the stellar initial mass function (IMF) from the superposition of mass distributions of dense cores, generated through gravoturbulent fragmentation of unstable clumps in molecu...
