Theories of the initial mass function [PDF]

open access: yesProceedings 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.

THE INITIAL MASS FUNCTION OF EARLY-TYPE GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2010
We determine an absolute calibration of the initial mass function (IMF) of early-type galaxies, by studying a sample of 56 gravitational lenses identified by the SLACS Survey. Under the assumption of standard Navarro, Frenk & White dark matter halos, a combination of lensing, dynamical, and stellar population synthesis models is used to disentangle

The Initial Mass Function as given by the fragmentation [PDF]

open access: yesAstronomische 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 reviewed.

The Dawes Review 8: Measuring the Stellar Initial Mass Function [PDF]

open access: yesPublications Astronomical Society of Australia, 2018
The birth of stars and the formation of galaxies are cornerstones of modern astrophysics. While much is known about how galaxies globally and their stars individually form and evolve, one fundamental property that affects both remains elusive.

A nonextensive insight into the stellar initial mass function [PDF]

open access: yesEPL (Europhysics Letters), 2019
the present paper, we propose that the stellar initial mass distributions as known as IMF are best fitted by $q$-Weibulls that emerge within nonextensive statistical mechanics. As a result, we show that the Salpeter's slope of $\sim$2.35 is replaced when a $q$-Weibull distribution is used.

Evidence for Universality in the Initial Planetesimal Mass Function [PDF]

open access: yesThe Astrophysical Journal Letters, 2017
Abstract Planetesimals may form from the gravitational collapse of dense particle clumps initiated by the streaming instability. We use simulations of aerodynamically coupled gas–particle mixtures to investigate whether the properties of planetesimals formed in this way depend upon the sizes of the particles that participate in the ...
