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).

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 ...

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 ...

Toward an initial mass function for giant planets [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The distribution of exoplanet masses is not primordial. After the initial stage of planet formation is complete, the gravitational interactions between planets can lead to the physical collision of two planets, or the ejection of one or more planets from

Constraining the Initial Mass Function via Stellar Transients
UniverseThe stellar initial mass function (IMF) represents a fundamental quantity in astrophysics and cosmology describing the mass distribution of stars from low mass all the way up to massive and very massive stars. It is intimately linked to a wide variety of

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.

Fragmentation and the initial mass function [PDF]
International Astronomical Union Colloquium, 1989 A central problem in the theory of star formation is to understand the spectrum of masses, or Initial Mass Function, with which stars are formed. The fundamental role of the IMF in galactic evolution has been described by Tinsley (1980), and an extensive review of evidence concerning the IMF and its possible variability has been presented by Scalo ...

A two-step initial mass function: [PDF]
Astronomy & Astrophysics, 2001 If stars originate in transient bound clusters of moderate size, these clusters will decay due to dynamic interactions in which a hard binary forms and ejects most or all the other stars. When the cluster members are chosen at random from a reasonable initial mass function (IMF), the resulting binary characteristics do not match current observations ...
