Corana, Core, and Radiative zone
|
Detailed explanation-1: -The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.
Detailed explanation-2: -Just outside the Inner Core of the sun at a distance approximately 0.25 to 0.7 solar radii lies the Radiative Zone. This zone radiates energy through the process of photon emission and capture by the hydrogen and helium ions.
Detailed explanation-3: -In the Sun, the region between the solar core at 0.2 of the Sun’s radius and the outer convection zone at 0.71 of the Sun’s radius is referred to as the radiation zone, although the core is also a radiative region. The convection zone and the radiation zone are divided by the tachocline, another part of the Sun.
