Is there a stellar upper mass limit? Recent statistical work seems to indicate that there is and that it is in the vicinity of 150 M☉. In this paper we use HST and ground-based data to investigate the brightest members of the cluster Pismis 24, one of which (Pismis 24-1) was previously inferred to have a mass greater than 200 M☉, in apparent disagreement with that limit. We determine that Pismis 24-1 is composed of at least three objects, the resolved Pismis 24-1SW and the unresolved… Expand

TOWARD A UNIFICATION OF STAR FORMATION RATE DETERMINATIONS IN THE MILKY WAY AND OTHER GALAXIES
The star formation rate (SFR) of the Milky Way remains poorly known, with often-quoted values ranging from 1 to 10 Myr −1 . This situation persists despite the potential for the Milky Way to serve as… Expand
The massive stellar population in the young association LH 95 in the Large Magellanic Cloud
We present a spectroscopic study of the most massive stars in the young (4 Myr old) stellar cluster LH 95 in the Large Magellanic Cloud. This analysis allows us to complete the census of the stellar… Expand
TOWARD AN ACCURATE DETERMINATION OF PARAMETERS FOR VERY MASSIVE STARS: THE ECLIPSING BINARY LMC-SC1-105*
This paper presents a photometric and spectroscopic study of the bright blue eclipsing binary LMC-SC1-105, selected from the Optical Gravitational Lensing Experiment catalog as a candidate host of… Expand
A multifrequency study of the active star-forming complex NGC 6357 – I. Interstellar structures linked to the open cluster Pis 24
We investigate the distribution of the gas (ionized, neutral atomic and molecular), and interstellar dust in the complex star forming region NGC6357 with the goal of studying the interplay between… Expand
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… Expand
Biases on Initial Mass Function Determinations. II. Real Multiple Systems and Chance Superpositions
When calculating stellar initial mass functions (IMFs) for young clusters, one has to take into account that (1) most massive stars are born in multiple systems, (2) most IMFs are derived from data… Expand
High-resolution imaging of Galactic massive stars with AstraLux. I. 138 fields with δ > - 25°
Context. Massive stars have high-multiplicity fractions, and many of them have still undetected components, thus hampering the study of their properties. Aims. I study a sample of massive stars with… Expand
The mmax-Mecl relation, the IMF and IGIMF: probabilistically sampled functions?
We introduce a new method to measure the dispersion of mmax values of star clusters and show that the observed sample of mmax is inconsistent with random sampling from an universal stellar initial… Expand
VLT/FLAMES-ARGUS observations of stellar wind–ISM cloud interactions in NGC 6357
We present optical/near-IR integral field unit observations of a gas pillar in the Galactic H ii region NGC 6357 containing the young open star cluster Pismis 24. These observations have allowed us… Expand

A truncated power-law distribution is fitted to the 29 largest stellar masses known in R136. Two different statistical techniques are used, with comparable results. An upper limit to the mass… Expand
Statistical confirmation of a stellar upper mass limit
We derive the expectation value for the maximum stellar mass (mmax) in an ensemble of N stars, as a function of the initial mass function (IMF) upper mass cutoff (mup) and N. We statistically… Expand
Evidence for a fundamental stellar upper mass limit from clustered star formation

An upper limit to the masses of stars
TLDR
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. Expand
