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.

Impact of metallicity and star formation rate on the time-dependent, galaxy-wide stellar initial mass function [PDF]

open access: yesAstronomy & Astrophysics, 2018
The stellar initial mass function (IMF) is commonly assumed to be an invariant probability density distribution function of initial stellar masses. These initial stellar masses are generally represented by the canonical IMF, which is defined as the ...

The stellar initial mass function of the solar neighbourhood revealed by Gaia [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
I use a sample of more than 120 000 stars in the solar neighbourhood, with parallaxes, magnitudes and colours estimated with unprecedented accuracy by the second data release of the Gaia mission, to derive the initial mass function of the Galactic disc.

Faint Stars in a Faint Galaxy. II. The Low-mass Stellar Initial Mass Function of the Boötes I Ultrafaint Dwarf Spheroidal Galaxy

open access: yesThe 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.

Simulating star clusters across cosmic time – I. Initial mass function, star formation rates, and efficiencies [PDF]

open access: yesMonthly 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.

The Initial Mass Function of Be Stars [PDF]

open access: yesSymposium - 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 ...
