Episodic ejection from a low-mass YSO traced by H2O masers
We request EVN observations of the 22 GHz H2O maser in a prototypical low-mass protostellar system IRAS 16293-2422 to characterize the cause of the newly discovered enhanced maser activity and to study the source's ejection behavior as it traced by maser emission. Single-dish monitoring and analysis of archival data indicate that the activity of the H2O maser in IRAS 16293-2422 has a cyclic character and traces episodic ejection events in the source. A new maser flare was recently discovered in a spectral feature that has never shown such a significant increase in flux density before. The flare of this feature seems to indicate the beginning of a new cycle of activity.
