Evidence for Initial Mass Function Variation in Massive Early-Type Galaxies
, 2020The initial mass function (IMF), describing the distribution of birth masses of stars, plays a pivotal role in establishing the observable properties of galaxies.

As we have already heard, estimates of the fraction of a star-forming cloud that is converted into stars and of the overall star formation rate in galaxies depend crucially on the assumed stellar initial mass function, which must be known before any quantitative conclusions can be drawn about galactic evolution.

THE ORIGIN OF THE INITIAL MASS FUNCTION IS IN THE CLOUD STRUCTURE
2007Detailed knowledge of the initial distribution of stellar masses at birth (known as the initial mass function or IMF) is necessary to predict and understand the evolution of stellar systems, such as clusters and galaxies. Unfortunately, stellar evolution theory cannot predict the form of this critical function and the origin of the stellar IMF remains ...

Unresolved Binaries and the Initial Mass Function
Astrophysics and Space Science, 2002In the area of binary stars the important contribution of GAIA will be towards statistical studies of the binary star distribution functions. On the other hand, from the GAIA observations, more than 10 000 masses accurate to 1 % can be expected. This improves accuracy of the stellar initial mass function (IMF) still poorly known, particularly for the ...

The Initial Mass Function in the Galactic Bulge [PDF]
, 2005 We measured the IMF of the Galactic Bulge, down to ∼ 0.15M through NICMOS observations of a field near (l,b)=(0,-6). The derived IMF, the deepest measured to date in the Bulge, follows a power-law slope of α = −1.33± 0.07 (where Salpeter has α = −2.35). This result has negligible dependence on the adopted Bulge metallicity and distance modulus.
