The Most Fantastical Possibility That Explains Shabilski Star

The most ridiculous and funnest, but maybe also most plausible explanation is of course, aliens. We can create these things here on earth using our laboratories. Maybe they are generating energy from vision or they have some insane fusion process. The stuff is very radioactive. What should you do with it? Well, maybe they decided to like, eat it into the sun. And so they dumped it into their star. That's better than our current state, canal of chaos.
