The place of interferometry in massive star multiplicity sudies

TL;DR

This paper reviews the role of interferometry in studying the multiplicity of massive stars, highlighting the importance of complementary techniques to better understand their statistical properties.

Contribution

It clarifies the current status of massive star multiplicity research and discusses how interferometry can complement other methods to improve characterization.

Findings

Interferometry plays a crucial role in resolving close massive star systems.

Complementary techniques are essential for comprehensive statistical analysis.

Current challenges include covering the large parameter space of multiplicity.

Abstract

While it is well known that most massive stars are found to be part of binary or multiple systems, an accurate characterization of the statistical properties of these multiple objects is still lacking. In the present talk, we will review the current status of the field, emphasizing the need of using complementarity techniques to cover the large parameter space. We will also describe what we think is the place of interferometry in this context.
