Characterising the orbit and circumstellar environment of the high-mass binary MWC 166 A
Characterising the orbit and circumstellar environment of the high-mass binary MWC 166 A
Context. Stellar evolution models are highly dependent on accurate mass estimates, especially for highly massive stars in the early stages of stellar evolution. The most direct method for obtaining model-independent stellar masses is derivation from the orbit of close binaries. Aims. Our aim was to derive the first astrometric plus …
