Abstract
We report on the discovery and follow-up of the first disk-mediated accretion burst in a high-mass young stellar object (HMYSO), S255IR NIRS 3. Our results strengthen the idea that massive stars form through disks via episodic accretion, pointing to a common formation mechanism across the entire stellar mass spectrum. Moreover, our data reveal a tight correlation between the burst, the onset of a methanol maser flare and boosting of pre-existent radio jet emission.
