The Sun is about 4.6 billion years old and is about halfway through its main-sequence evolution, during which nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than 4 million tons of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation.
Solar Radiation
Solar radiation is radiant energy emitted by the sun, particularly electromagnetic energy. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.
Neutrinos
Because the cross section in weak nuclear interactions is very small, neutrinos can pass through matter almost unhindered. For typical neutrinos produced in the sun (with energies of a few MeV), it would take approximately one light year (~1016m) of lead to block half of them. Detection of neutrinos is therefore challenging, requiring large detection volumes or high intensity artificial neutrino beams.

there is no heat round the sun, only waves and particles. in fact it is ice cold. the waves need matter to be converted into heat.

Hot.
(It's alright, I've just taken a crash course in **** answers from some of the answers I've seen so far today)

Heat is a heat. No seperate name.

Maybe this has your answer?
Generally the outer layer is called the corona and it is hotter than some of the inner layers. So maybe that's what you are looking for.
