High resolution observations of Massive Young Stellar Objects

Young massive stars have the power to influence their surroundings from local to galactic scales. Despite this, their rarity and deeply embedded nature has limited our understanding of their formation. Indeed, questions such as binary star formation and the accretion mechanisms are still largely unanswered. High resolution work on single objects has given us valuable snapshots of the massive star formation process, but the results so far have been largely anecdotal.
In this talk I will first present our results on binary star formation, including the discovery of the closest Young Massive Binary to date. I will then proceed discussing the results obtained of a high resolution mini-survey of ~10 MYSOs combined with 3D radiative transfer models. This is the largest sample analysed with such a dataset, and I conclude discussing the resultant implications for massive star formation.
