Multiplicity of northern bright O-type stars with optical long baseline interferometry
Multiplicity of northern bright O-type stars with optical long baseline interferometry
The study of the multiplicity of massive stars gives hints on their formation processes and their evolutionary paths, which are still not fully understood. Large separation binaries (>50 milliseconds of arc, mas) can be probed by adaptive-optics-assisted direct imaging and sparse aperture masking, while close binaries can be resolved by …
