On the variation of the Initial Mass Function [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 (shortened) In this contribution an average or Galactic-field IMF is defined, stressing that there is evidence for a change in the power-law index at only two masses: near 0.5 Msun and 0.08 Msun.

A discontinuity in the low-mass initial mass function [PDF]
The Astrophysical Journal, 2007 The origin of brown dwarfs (BDs) is still an unsolved mystery. While the standard model describes the formation of BDs and stars in a similar way recent data on the multiplicity properties of stars and BDs show them to have different binary distribution ...

Theories of the initial mass function [PDF]
Proceedings of the International Astronomical Union, 2010 We review the various theories which have been proposed along the years to explain the origin of the stellar initial mass function. We pay particular attention to four models, namely the competitive accretion and the theories based respectively on ...

Extragalactic Constraints on the Initial Mass Function [PDF]
Monthly Notices of the Royal Astronomical Society, 2008 The local stellar mass density is observed to be significantly lower than the value obtained from integrating the cosmic star formation history (SFH), assuming that all the stars formed with a Salpeter initial mass function (IMF).

Clump Lifetimes and the Initial Mass Function [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Recent studies of dense clumps/cores in a number of regions of low-mass star formation have shown that the mass distribution of these clumps closely resembles the initial mass function (IMF) of field stars.

The Initial Mass Function: Now and Then
AIP Conference Proceedings, 1996 We examine whether existing data in clusters, both old and young, and in the field of the Galactic disk and halo is consistent with a universal slope for the initial mass function (IMF).

The Role of Magnetic Fields in Setting the Star Formation Rate and the Initial Mass Function [PDF]
Frontiers in Astronomy and Space Sciences, 2019 Star-forming gas clouds are strongly magnetized, and their ionization fractions are high enough to place them close to the regime of ideal magnetohydrodyamics on all but the smallest size scales.

The Initial Mass Function as given by the fragmentation [PDF]
Astronomische Nachrichten, 2005 The dichotomy between a universal mass function (IMF) and a variable IMF which depends on local physical parameters characterises observational and theoretical stellar astronomy. In this contribution the available distributions of probability are briefly

Initial mass function of intermediate mass black hole seeds [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 We study the Initial Mass Function (IMF) and host halo properties of Intermediate Mass Black Holes (IMBH, 10^{4-6} Msun) formed inside metal-free, UV illuminated atomic cooling haloes (virial temperature T_vir > 10^4 K) either via the direct collapse of ...
