TL;DR
This paper reviews spectroscopic monitoring of Galactic O and WN stars, focusing on detecting radial-velocity variations that suggest orbital motion, providing insights into their binary nature and stellar dynamics.
Contribution
It presents early results from spectroscopic monitoring aimed at identifying binary systems among O and WN stars in our Galaxy.
Findings
Detection of radial-velocity variations in some stars
Evidence supporting the presence of binary systems
Methodology for spectroscopic monitoring of massive stars
Abstract
We are conducting a spectroscopic monitoring of O and WN -type stars in our Galaxy. In this work, we summarize some of our first results related to the search for radial-velocity variations indicative of orbital motion.
