Search for Faint Companions to O-Stars Using the AEOS 3.6 Meter Telescope

Abstract

O stars are the most massive and luminous main sequence stars in the sky. they are frequently found in clusters of other O and B type stars. Due to the intrinsic brightness of these stars and their typical large distances, physical companions found by traditional techniques (spectroscopy, speckle interferometry, etc.) tend to be similar in mass and brightness to the primary. Adaptive optics observations allow one to probe for the fainter physical companions, further testing star formation scenarios and neighborhood conditions of O and B star clusters. We present the results of a multi-year survey of O stars using the Advanced Electro-Optical System (AEOS) 3.6-meter telescope specifically searching for additional companions.
