Electric Current in a Close Binary Star

This article mentioned interesting gravity waves from these close together binarys. It also mentioned a plume of matter jetting from one star to the other.

I know very little about astronomy so forgive how naive this may sound.
So my question is:
What about the electric current between these two objects?



The picture shows a plume of matter jetting from one of the binarys to the other. Would a massive electric charge be running up and down this plume? I mean truly cataclysmic looking lightning (although I don't think there is lightning without an atsmosphere.) However there would be star dust and gas to arc I would think. Would this binary act like a gigantic generator?


Can anyone explain what is happening electrically in a close together binary star such as this where it appears they actually share matter with eachother?
