ORBITS, DISTANCE, AND STELLAR MASSES OF THE MASSIVE TRIPLE STAR σ ORIONIS
ORBITS, DISTANCE, AND STELLAR MASSES OF THE MASSIVE TRIPLE STAR σ ORIONIS
ABSTRACT We present interferometric observations of the σ Orionis triple system using the CHARA Array, NPOI, and VLTI. Using these measurements, we spatially resolve the orbit of the close spectroscopic binary (Aa,Ab) for the first time and present a revised orbit for the wide pair (A,B). Combining the visual orbits …
