Yep, Nickel and Iron, but that was known over 75 years ago.

The sun is an average star with a mass equal to nearly one-third of a million Earths. It is made up of almost 80% hydrogen by mass and is entirely gaseous, although the gas near its center is under such tremendous pressure, it behaves like a fluid.

In the astronomy course I took about 25 years ago, they said that iron doesn't burn too well.

As the fusion process starts running out of the lighter elements, and begins to burn iron, the star changes dramatically.
Supernova in the large stars, red giant in the smaller.

So I find it hard to believe that our star has any appreciable percentage of iron at this time.

Shouldn't spectrography be able clarify the issue?

Wouldn't it would change all sorts of assumptions about the mass of the Sun?
