Witryna4 sie 2024 · The resulting IMF is top-heavy with a slope even shallower than that in Fig. 5a. Interestingly, these assumptions tend to agree with the model of Clark & Whitworth (2024), which combines turbulent fragmentation and competitive accretion. The high-mass end of the predicted core fragmentation mass functions is broadly invariant over … Witrynatop-heavy IMF in the resolved population (Stolte et al., 2005). Caveats are that this may be influenced by mass seg-regation in the cluster, incompleteness, and perhaps unre-solved binaries. The second case is the galactic center, where the massive stars are resolved (Paumard et al., 2006), but there appears little evidence for a low-mass pre ...

Witrynatogether with a top-heavy IMF and a 10% retention fraction for remnants, a better agreement to the data can be obtained (Zonoozi et al. 2016), and incorporating the age–metallicity relation further improves the fit (Haghi et al. 2024). Moreover, Banerjee & Kroupa (2012) found that the top-heaviness of the true high-mass IMF over the ...

Witryna11 kwi 2024 · The IMF now envisions growth this year of 2.8%, down from 3.4% in 2024 and from the 2.9% estimate for 2024 it made in its previous forecast in January. High interest rates weaken growth WitrynaEvidence for abnormal IMFs in some starburst galaxies is reviewed. Recent determinations of the near-infrared extinction in M82 weaken, or at least complicate, the suggestion that a large lower mass limit m l is required to account for the 2µm luminosity.

An IMF biased in favor of massive stars has been suggested previously by Sage et al. ( 1991 ), Henkel & Mauersberger ( 1993 ), and Papadopoulos et al.
