The multiplicity of massive stars in the Scorpius OB1 association through high-contrast imaging

Tinne Pauwels, Maddalena Reggiani, Hugues Sana +2

One of the most remarkable properties of massive stars is that almost all of them are found in binaries or higher-order multiple systems. Observations that cover the full companion…

On the origin of close massive binaries in the M17 star-forming region

E. Bordier, A. J. Frost, H. Sana +5

Spectroscopic multiplicity surveys of O stars in young clusters and OB associations have revealed that a large portion ( 70%) of these massive stars (M 15 $M_{\od…

Probing the low-mass end of the companion mass function for O-type stars

M. Reggiani, A. Rainot, H. Sana +6

Almost all massive stars are part of a binary system. Given the wide range of separations at which these companions are found, several observational techniques have been adopted to…

The Carina High-contrast Imaging Project for massive Stars (CHIPS): II. O stars in Trumpler~14

Alan Rainot, Maddalena Reggiani, Hugues Sana +2

Most massive stars belong to multiple systems, yet the formation process leading to such high multiplicity remains insufficiently understood. To help constrain the different format…

The Carina High-Contrast Imaging Project for massive Stars (CHIPS) I. Methodology and proof of concept on QZ Car ( HD93206)

A. Rainot, M. Reggiani, H. Sana +13

Massive stars like company. However, low-mass companions have remained extremely difficult to detect at angular separations () smaller than 1" (~1000-3000 au considering typical…
