What happened to saying it "appears" to have a hydrogen side and a helium side?

I'm just some guy, but a ball of plasma rotating every 15 minutes seems highly unlikely to be separated vertically into two materials of different weights.

It hardly seems like they're applying Occam's Razor here.

From the article: "One explanation is that Janus could be undergoing a rare transition that has been predicted to occur during white dwarf evolution."

So it does fall within the known models.
