Composite powerful short flare of water maser emission in IRAS 16293-2422
ABSTRACT Using long-term monitoring data of water-vapour masers, here we examine a composite powerful flare of extremely short duration (∼12 d), which occurred in IRAS 16293-2422. The most powerful part of the flare was located on top of a less strong but more prolonged flare, which in turn is also...

| description | ABSTRACT
Using long-term monitoring data of water-vapour masers, here we examine a composite powerful flare of extremely short duration (∼12 d), which occurred in IRAS 16293-2422. The most powerful part of the flare was located on top of a less strong but more prolonged flare, which in turn is also a composite. The configuration of three radiating maser condensations located on the line of sight to the observer was detected for the first time. This made it possible to confirm one of the hypotheses for the activation of water masers, based on an increase in the maser’s amplification length by the components located in the observer’s line of sight. The unsaturated state of the two most powerful maser flares have been confirmed and some significant water maser parameters were obtained. |
