IMF AND EVOLUTION OF CLOSE BINARIES AFTER STARFORMATION BURSTS
Odessa Astronomical Publications, 2017 This paper is a continuation and development of our previous articles (Popov et al., 1997, 1998). We use Scenario "Machine" (Lipunov et al., 1996b) - the population synthesis simulator (for single binary systems calculations the program is available in ...

The Stellar IMF of Galactic Clusters and Its Evolution [PDF]
, 2007 We show that one can obtain a good fit to the measured main sequence mass function (MF) of a large sample of Galactic clusters (young and old) with a tapered Salpeter power law distribution function with an exponential truncation. The average value of the power law index is very close to Salpeter (~2.3), whereas the characteristic mass is in the range ...

Dynamical evolution of star clusters with top-heavy IMF [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractSeveral observational and theoretical studies suggest that the initial mass function (IMF) slope for massive stars in globular clusters (GCs) depends on the initial cloud density and metallicity, such that the IMF becomes increasingly top-heavy with decreasing metallicity and increasing the gas density of the forming object.

On being grandmotherly: The evolution of IMF conditionality [PDF]
CEPAL Review, 1982 The principle of conditionality has always been at the centre of the controversy over the influence the International Monetary Fund should wield over national policies in connexion with its loans, to such a point that there were animated arguments on the matter during the negotiations to establish the IMF, not only between the European countries and ...

The Chemical Evolution of the Galaxy with Variable IMFs
, 1999 In this work we explore the effects of adopting initial mass functions (IMFs) variable in time on the chemical evolution of the Galaxy. In order to do that we adopt a chemical evolution model which assumes two main infall episodes for the formation of the Galaxy and which proved to be successful in reproducing the majority of the observational ...

Metals, 2019 The current study observed a grain structure evolution in the central part and periphery of the sample of an Al–Mg–Mn-based alloy during isothermal multidirectional forging (IMF) at 350 °C with a cumulative strain of 2.1–6.3 and a ...

Direct Evidence for Stellar Initial Mass Function Variation in the Milky Way
The Astrophysical Journal LettersBecause direct measurements require resolved stellar populations, including low-mass stars, determining the stellar initial mass function (IMF) has been a historically difficult problem even within our own Galaxy, and impossible everywhere else.

Astronomy & AstrophysicsGrowing evidence suggests that the stellar initial mass function (IMF) varies systematically across galaxies, deviating from the canonical Milky Way form.

Animal, 2019 Intramuscular fat (IMF) content depends on sex, genotype and diet and varies with pig growth. The aim of the present work was to determine the evolution of IMF by genotype-sex, muscle and muscle location, to determine relationships between IMF content of
