Magnetic Stress of Active Regions and Speed of Ejections

What is it about?

Active regions surrounding sunspots tend to erupt when their magnetic fields become highly stressed. In this paper, we try to relate different parameters that are stress indicators to see which of these are better related to the speed of the ejected material resulting from the eruption.

Why is it important?

This work appears at a time when the community is grappling with the issue of identifying the drivers of these ejections. Since it is a comprehensive study of several active regions and several parameters, it will be very useful for other investigators.
