Theories of the initial mass function [PDF]

Proceedings of the International Astronomical Union, 2010
AbstractWe 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 stopped accretion, MHD shocks and turbulent dispersion.

Inferring Globular Cluster Initial Mass Function from Stellar Streams

The Astrophysical Journal Letters
The Gaia mission has provided precise astrometry and spectrophotometry for billions of stars in the Milky Way, enabling the identification and kinematic characterization of stellar streams. These streams, remnants of disrupted globular clusters and dwarf

Substellar initial mass function of Trumpler 14

Astronomy & Astrophysics
Context. Young, massive stellar clusters offer a prime setting to explore brown dwarf (BD) formation under high densities and intense UV radiation. Trumpler 14 (Tr 14), a ∼1 Myr old cluster located at a distance of 2.4 kpc that is particularly rich in O ...

Constraining the Initial Mass Function in the Epoch of Reionization from Astrophysical and Cosmological Data

Universe
We aim to constrain the stellar initial mass function (IMF) during the epoch of reionization. To this purpose, we build up a semi-empirical model for the reionization history of the Universe based on various ingredients: the latest determination of the ...

Does turbulence determine the initial mass function? [PDF]

, 2016
We test the hypothesis that the initial mass function (IMF) is determined by the density probability distribution function (PDF) produced by supersonic turbulence.

Probing the Milky Way Stellar and Brown Dwarf Initial Mass Function with Modern Microlensing Observations

The Astrophysical Journal Letters, 2023
We use recent microlensing observations toward the central bulge of the Galaxy to probe the overall stellar plus brown dwarf initial mass function (IMF) in these regions well within the brown dwarf domain. We find that the IMF is consistent with the same
