The Initial Mass Function of Be Stars [PDF]
Symposium - International Astronomical Union, 2004 Allowing for systematic differences in the counting of Be Stars due to their overluminosity, changes produced by their fast rotation on spectral types and time spent in the main sequence, a difference between the IMF (Be) and IMF(B) appears, which indicates that the appearance of the Be phenomenon may relay on differences in the initial star formation ...

The low-mass Initial Mass Function in the young cluster NGC 6611 [PDF]
, 2008 NGC 6611 is the massive young cluster (2-3 Myr) that ionises the Eagle Nebula. We present very deep photometric observations of the central region of NGC 6611 obtained with the Hubble Space Telescope and the following filters: ACS/WFC F775W and F850LP ...

Simulating star clusters across cosmic time – I. Initial mass function, star formation rates, and efficiencies [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present radiation-magneto-hydrodynamic simulations of star formation in self-gravitating, turbulent molecular clouds, modelling the formation of individual massive stars, including their UV radiation feedback.

Fragmentation and the initial mass function [PDF]
International Astronomical Union Colloquium, 1989 A central problem in the theory of star formation is to understand the spectrum of masses, or Initial Mass Function, with which stars are formed. The fundamental role of the IMF in galactic evolution has been described by Tinsley (1980), and an extensive review of evidence concerning the IMF and its possible variability has been presented by Scalo ...

On the black hole content and initial mass function of 47 Tuc [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The globular cluster (GC) 47 Tuc has recently been proposed to host an intermediate-mass black hole (IMBH) or a population of stellar mass black holes (BHs).

The initial mass function of a massive relic galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Massive relic galaxies formed the bulk of their stellar component before z ~ 2 and have remained unaltered since then. Therefore, they represent a unique opportunity to study in great detail the frozen stellar population properties of those galaxies that populated the primitive Universe.

The Astrophysical Journal, 2022 This paper presents improved constraints on the low-mass stellar initial mass function (IMF) of the Boötes I (Boo I) ultrafaint dwarf galaxy, based on our analysis of recent deep imaging from the Hubble Space Telescope.

Initial mass function variations cannot explain the ionizing spectrum of low metallicity starbursts [PDF]
Astronomy & Astrophysics, 2018 Aims. Observations of both galaxies in the distant Universe and local starbursts are showing increasing evidence for very hard ionizing spectra that stellar population synthesis models struggle to reproduce.

The stellar population and initial mass function of NGC 1399 with MUSE [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We present spatially resolved measurements of the stellar initial mass function (IMF) in NGC1399, the largest elliptical galaxy in the Fornax Cluster.
