Solar Interior: Solar Diameter, Oblateness and Temperature
Abstract
The visible edge of the Sun is called the LIMB and is almost circular, but very small deviations from a spherical Sun are measurable. The largest deviation is a `flattening' of the polar radius in comparison to the equatorial solar radius. The Sun's surface temperature is also not spherically symmetric but has a tiny asphericity in the form of a latitudinal temperature variation. The radius, sha...
