# The multiplicity of massive stars: a 2016 view

## TL;DR

This paper reviews recent advances in understanding the multiplicity of massive stars, highlighting new observational insights, formation constraints, and implications for their evolution over the past five years.

## Contribution

It synthesizes recent survey results to improve understanding of massive star multiplicity, formation conditions, and evolutionary outcomes.

## Key findings

- Increased observational data on massive star multiplicity
- New constraints on star formation processes
- Insights into the evolution of massive binary systems

## Abstract

Massive stars like company. Here, we provide a brief overview of progresses made over the last 5 years by a number of medium and large surveys. These results provide new insights on the observed and intrinsic multiplicity properties of main sequence massive stars and on the initial conditions for their future evolution. They also bring new interesting constraints on the outcome of the massive star formation process.
