Flaring water masers in MYSO S255 NIRS3 - a sign of another accretion ev
This June, the high-mass young stellar object (MYSO) S255 NIRS 3 underwent a water maser flaring episode, the third which has been recorded since the late 80s. In 2015, the target underwent an episodic accretion event after which it flared in 6.7 GHz methanol masers. Unfortunately no water maser observations were performed at the time of the 2015 burst, but only months later, not finding any evidence of a water maser flare. However, in other MYSOs water and methanol have been seen flaring quasi simultaneously, indicating that also water masers might be connected to accretion events. EVN+e-MERLIN polarimetric observations are requested to map the distribution of the water maser velocity components in S255 NIRS 3 to search for evidence of an accretion event by comparing the post-burst distribution to archival pre-burst EVN data from 2019.
