Chemical evolution of elliptical galaxies with a variable IMF [PDF]
Astronomy and Astrophysics, 2019 Growing evidence in recent years suggests a systematic variation of the stellar initial mass function (IMF), being top-heavy for starburst galaxies and possibly bottom-heavy for massive ellipticals. Galaxy chemical evolution simulations adopting an invariant canonical IMF face difficulty in simultaneously reproducing the metallicity and α-enhancement ...

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 ...

What went wrong? The evolution of the IMF 1941-1961
PSL Quarterly Review, 2013 Despite its promising start in 1946-47, the new IMF soon ceased to fulfil its expected role for almost nine years. An exploration is provided for the latter in the wider context of international economic cooperation. It was not until 1961 that the Fund's

Evolution of the magnetic field structure outside the magnetopause under radial IMF conditions [PDF]
Journal of Geophysical Research: Space Physics, 2017 AbstractWe use the Time History of Events and Macroscale Interactions during Substorms data to investigate the magnetic field structure just outside the magnetopause and its time evolution for radial interplanetary magnetic field (IMF) events. When the magnetic field drapes around the magnetopause in the magnetosheath region, an asymmetric magnetic ...

Managing House Price Booms: Evolution of IMF Surveillance and Policy Advice [PDF]
, 2019 AbstractThis chapter describes the evolution of IMF monitoring—“surveillance” in the IMF’s jargon—of housing markets from 2008 to the present. It explains how the IMF has assessed overvaluation in housing markets and the advice offered on the policy tools needed to manage house price booms.

The Astrophysical Journal, 2023 The stellar initial mass function (IMF) is expressed by ϕ ( m ) ∝ m ^− ^α with the slope α , and known as a poorly constrained but very important function in studies of star and galaxy formation. There are no sensible observational constraints on the IMF

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 ...

Earth and Planetary Physics, 2020 Proton cyclotron waves (PCWs) can be generated by ion pickup of Martian exospheric particles in the solar wind. The solar wind ion pickup process is highly dependent on the “IMF cone angle” — the angle between the solar wind velocity and the ...
