Very interesting. Looking forward to the theories of what's going on.

Assymetry implies structural instability to me.

Maybe some kind of lop sided CME?

The outer layers are very loosely held by the low surface gravity. The slightest push and pull can set it wobbling like a giant soap bubble in the wind.

The internals have instabilities due to changing opacity with temperature and pressure leading to the multiple oscillations and periods seen.

t's a very dynamic atmosphere. The core is not impacted much by all this which is why the latest changes probably don't have anything to do with it going SN any time soon.
