I kinda study SNe Ia and find the super-Chandrasekhar-mass ones interesting, so I'm getting a kick out of this.

Dunno whether their idea will be more provable than the idea of two white dwarves merging ("double-degenerate") and thus exceeding the limit, which I've heard a lot before.

jamspoon: So if type Ia supernovae may be Ia+ does that mean the theory of expansion is in doubt? There could be a few relived physicists if it is.


At the end of the article they discuss this.  And no, it probably doesn't mess up dark energy related calculations.  Such weird supernovae are likely too rare to account for dark energy observations, and it is pretty easy to pick out these supernovae and remove them.

I suppose you could argue that these strange supernovae could have been more numerous in the early universe, which would mess things up.  So it needs to be looked into.  But the bottom line is that, from what we know, this doesn't really do much to dark energy calculations.

What a Chandraskehar  investigating a broken limit may look like.
