A Stellar Outburst Was Still Lighting Masers Ten Years Later
Water masers remained elevated as methanol and hydroxyl emission approached quiescence.
Summary
Water masers remained elevated as methanol and hydroxyl emission approached quiescence.
Monitoring of NGC 6334I-MM1 finds maser activity persisting a decade after its 2015 accretion outburst. Infrared expansion was estimated near 1.8 AU per day radially and about ten times faster along the north–south outflow. Quasi-periodic 12.2-gigahertz methanol emission appeared after the event, though its exact location among the region's sources remains uncertain.
Why it matters
Water masers remained elevated as methanol and hydroxyl emission approached quiescence.
Limits and context
No additional limitation was separately recorded.
Key claims
