The observed masses of the most massive stars do not surpass about 150 M ○. . This may either be a fundamental upper mass limit which is defined by the physics of massive stars and/or their formation, or it may simply reflect the increasing sparsity of such very massive stars, so that the observation of even higher mass stars becomes unlikely in the Galaxy and the Magellanic Clouds. It is shown here that if the stellar initial mass function (IMF) is a power law with a Salpeter exponent (a = 2…

An upper limit to the masses of stars
There is an absence of stars with initial masses greater than 130 M [circdot] in the Arches cluster, whereas the typical mass function predicts 18.5; it is concluded that this indicates a firm limit of 150‬M [ Circdot] for stars.
Wind modelling of very massive stars up to 300 solar masses
The stellar upper-mass limit is highly uncertain. Some studies have claimed there is a universal upper limit of ∼150 M� . A factor that is often overlooked is that there might be a significant
The maximum stellar mass, star-cluster formation and composite stellar populations
We demonstrate that the mass of the most massive star in a cluster correlates non-trivially with the cluster mass. A simple algorithm, according to which a cluster is filled up with stars that are
An excess of massive stars in the local 30 Doradus starburst
The recent formation history and the initial mass function (IMF) of massive stars in 30 Doradus is determined on the basis of spectroscopic observations of 247 stars more massive than 15 solar masses, and the main episode of massive star formation began about 8 million years ago and seems to have declined in the last 1 My.
The stellar and sub-stellar IMF of simple and composite populations
The current knowledge on the stellar IMF is documented. It appears to become top-heavy when the star-formation rate density surpasses about 0.1Msun/(yr pc^3) on a pc scale and it may become
The influence of multiple stars on the high-mass stellar initial mass function and age-dating of young massive star clusters
The study of young stellar populations has revealed that most stars are in binary or higher order multiple systems. In this study, the influence on the stellar initial mass function (IMF) of large
The variation of integrated star initial mass functions among galaxies
The integrated galaxial initial mass function (IGIMF) is the relevant distribution function containing the information on the distribution of stellar remnants, the number of supernovae, and the
A possible origin of the mass–metallicity relation of galaxies
Observations show that galaxies follow a mass-metallicity relation over a wide range of masses. One currently favoured explanation is that less massive galaxies are less able to retain the gas and
Top-heavy integrated galactic stellar initial mass functions in starbursts
Star formation rates (SFRs) larger than 1000 Myr −1 are observed in extreme starbursts. This leads to the formation of star clusters with masses >10 6 Min which crowding of the pre-stellar cores may
Models for the Formation of Massive Stars
The formation of massive stars is currently an unsolved problems in astrophysics. Understanding the formation of massive stars is essential because they dominate the luminous, kinematic, and chemical


Statistical sampling from the stellar initial mass function (IMF) for all star-forming regions in the Galaxy would lead to the prediction of ~1000 M☉ stars unless there is a rapid turn-down in the
The Initial Mass Function of Stars: Evidence for Uniformity in Variable Systems
Combining IMF estimates for different populations in which the stars can be observed individually unveils an extraordinary uniformity of the IMF, which appears to hold for populations including present-day star formation in small molecular clouds.
Formation of massive binaries
The formation of massive stars is one of the major unsolved problems in stellar astrophysics. However, only few if any of these are found as single stars, on average massive stars have more than one
On the variation of the initial mass function
A universal initial mass function (IMF) is not intuitive, but so far no convincing evidence for a variable IMF exists. The detection of systematic variations of the IMF with star-forming conditions
On the formation of massive stars
A B STR A CT We present a model for the formation of massive (Mz10 M>) stars through accretion-induced collisions in the cores of embedded dense stellar clusters. This model circumvents the problem
Conditions for the Formation of Massive Stars through Nonspherical Accretion
Formation of massive stars through spherical accretion has been predicted to occur only in clouds which are nearly dust-free and can provide an extremely high accretion rate. It is shown that such
M82-F: a doomed super star cluster?
We present high dispersion echelle spectroscopy of the very luminous, young super star cluster (SSC) ‘F’ in M82, obtained with the 4.2-m William Herschel Telescope (WHT), for the purpose of deriving
Conditions for the formation of massive stars
Upper limits on the masses of stars that can form are reexamined and models for the inflow of matter through cocoons around stars of 60, 100, and 200 solar masses are calculated. Consideration is
Star Formation in R136: A Cluster of O3 Stars Revealed by Hubble Space Telescope Spectroscopy*
The R136 cluster in 30 Doradus is the prototype super star cluster, and the only example sufficiently close that its massive star content can be studied directly. We have used the Hubble Space
On the mass function of star clusters
Clusters that form in total 10 3 <N <10 5 stars (type II clusters) lose their gas within a dynamical time as a result of the photo-ionising flux from O stars. Sparser (type I) clusters get rid of
