The Sun is a ball of Iron (well, mostly iron)

Two Models of the Sun

Properties Standard Solar Model New Solar Model Origin

The sun formed instantly as a homogeneous body from an interstellar cloud with no mass accretion or mass loss.

The sun formed in a timely manner by accretion of fresh supernova debris on the collapsed core of a supernova.

Main source of luminosity

Hydrogen-fusion in the core

Energy from a supernova core

Main nuclear reactions

Hydrogen fusion:

4 1H + 2 e- —> 4He + 2 v + 27 MeV

Neutron emission:

<1n> —> 1n + 10 MeV

Neutron decay:

1n —> 1H + 0.8 MeV

Hydrogen fusion:

4 1H + 2 e- —> 4He + 2 v + 27 MeV

Energy from hydrogen fusion

Observable by-products of nuclear reactions

1. Neutrinos from the decay of fusion products in the core.

1. Neutrinos from the decay of fusion products in the core.



2. Hydrogen ions escape from the surface in the solar wind.

Major elements in the sun

Hydrogen, helium, carbon

Iron, nickel, oxygen, silicon

Comparable meteorites

None. Only about 0.1 % of the sun has the composition of carbonaceous chondrites.

About 99% of the sun has the same composition as ordinary meteorites.

Comparable planets

Giant planets far from the sun

Rocky planets close to the sun

* CNO neutrinos may be indicated by growth of the solar-wind 15N/14N ratio over geologic time.
