I Will the Sun end as a Type 1a supernova?

[swampwiz]

I had read that the Sun will become a white dwarf and then gradually cool down to a black dwarf, but this figure at Wikipedia says it will go supernova. (Yes, I know I should not trust Wikipedia, which is why I'm posting the question.)

but this figure at Wikipedia says it will go supernova.

It most certainly does not.

First of all, extrapolating conclusions from a general image is never a good idea.
(Btw even the image is not telling you what you think it's telling you: it says a sun-like star not Sun)

Second, it literally took me less than 1 min to find these two links:
https://en.wikipedia.org/wiki/Sun#After_core_hydrogen_exhaustion
https://en.wikipedia.org/wiki/Type_Ia_supernova

Isn't it a better practice to take a few minutes to research something, than to quickly open a thread and then spend a couple of hours waiting for a response?

I had read before that the Sun will not go supernova, but only asked the question because this figure says otherwise (which is what I had mentioned in the original posting). Are you trying to say that the figure is incorrect? Or perhaps the Sun is very close to being large enough to go supernova, but will barely not, etc.? Perhaps the Sun has a very non-normal composition of metals so that it will not go supernova, but that typical stars of the Sun's size do go supernova? I would hope that the confusion is appreciated here.

They are saying you are misinterpreting the figure. In fairness, it's not a great graphic.

For a Type 1A supernova, you need to have at least a binary star system. The white dwarf accretes matter from the other star until it builds up enough mass to trigger the supernova.
So for a Sun like star to ever produce a type 1A supernova, it has to have a companion star.

The picture is utterly confusing. It does not indicate evolution, just lists cases.

No, it doesn't. It really doesn't. This is your interpretation, not anything in the picture - which is illustrating another point entirely.

Since the source material for this thread is very sub-standard (not the OP's fault), this thread is closed.

I know this is locked, but to be more specific; the graphic appears to have a dashed line between the White Dwarf and 1a supernova, like this: ////// That, to me, says "maybe".
