We present a model for the formation of high-mass close binary systems in the context of forming massive stars through gas accretion in the centres of stellar clusters. A low-mass wide binary evolves under mass accretion towards a high-mass close binary, attaining system masses of the order of 30-50 M ○. at separations of the order of 1 au. The resulting high frequency of binary systems with two massive components is in agreement with observations. These systems are typically highly eccentric…

Stellar Encounters with Massive Star-Disk Systems
The dense, clustered environment in which massive stars form can lead to interactions with neighboring stars. It has been hypothesized that collisions and mergers may contribute to the growth of the
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
Stellar encounters involving massive stars in young clusters
We model collisions between pre-main-sequence stars using a smoothed particle hydrodynamics method. Assuming that all collisions lead to simple mergers, we use derived merger cross-sections to
Toward Understanding Massive Star Formation
AbstractAlthough fundamental for astrophysics, the processes that produce massive stars are not well understood. Large distances, high extinction, and short timescales of critical evolutionary phases
High-mass star formation by gravitational collapse of massive cores:
The current generation of millimeter interferometers have revealed a population of compact (r ∼< 0.1 pc), massive (M ∼ 100M ) gas cores that are the likely progenitors of massive stars. I review

Abstract I review theoretical models of star formation and how they apply across the stellar mass spectrum. Several distinct theories are under active study for massive star formation, especially
Star formation through gravitational collapse and competitive accretion
Competitive accretion, a process to explain the origin of the initial mass function (IMF), occurs when stars in a common gravitational potential accrete from a distributed gaseous component. Stars
Accretion-driven core collapse and the collisional formation of massive stars
We consider the conditions required for a cluster core to shrink, by adiabatic accretion of gas from the surrounding cluster, to densities such that stellar collisions are a likely outcome. We show
The Formation of Massive Stars
Abstract There has been considerable progress in our understanding of how massive stars form but still much confusion as to why they form. Recent work from several sources has shown that the
Forming spectroscopic massive protobinaries by disc fragmentation
The surroundings of massive protostars constitute an accretion disc which has numerically been shown to be subject to fragmentation and responsible for luminous accretion-driven outbursts. Moreover,


Accretion in stellar clusters and the collisional formation of massive stars
We present results from a numerical simulation of gas accretion in a cluster containing 1000 stars. The accretion forces the cluster to contract, leading to the development of a high-density core
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
The hierarchical formation of a stellar cluster
Recent surveys of star-forming regions have shown that most stars, and probably all massive stars, are born in dense stellar clusters. The mechanism by which a molecular cloud fragments to form
The formation of close binary systems by dynamical interactions and orbital decay
We present results from the first hydrodynamical star formation calculation to demonstrate that close binary stellar systems (separations 10 au) need not be formed directly by fragmentation. Instead,
Massive star formation: nurture, not nature
We investigate the physical processes that lead to the formation of massive stars. Using a numerical simulation of the formation of a stellar cluster from a turbulent molecular cloud, we evaluate the
The Birth of High-Mass Stars: Accretion and/or Mergers?
The observational consequences of the merger scenario for massive star formation are explored and contrasted with the gradual accumulation of mass by accretion. In high-density protostar clusters,
Competitive accretion in embedded stellar clusters
We investigate the physics of gas accretion in young stellar clusters. Accretion in clusters is a dynamic phenomenon as both the stars and the gas respond to the same gravitational potential.
The Formation of Massive Stars from Turbulent Cores
Observations indicate that massive stars in the Galaxy form in regions of very high surface density, � � 1 gc m � 2 . Clusters containing massive stars and globular clusters have a column density
Accretion in stellar clusters and the initial mass function
We present a simple physical mechanism that can account for the observed stellar mass spectrum for masses M∗≳0.5 M⊙. The model depends solely on the competitive accretion that occurs in stellar
The physics of star formation
Our current understanding of the physical processes of star formation is reviewed, with emphasis on processes occurring in molecular clouds like those observed nearby. The dense cores of these clouds
