Editing Radiative zone (section)

==Main sequence stars==
For [[main sequence]] stars—those stars that are generating energy through the [[thermonuclear fusion]] of hydrogen at the core, the presence and location of radiative regions depends on the star's mass. Main sequence stars below about 0.3 [[solar mass]]es are entirely convective, meaning they do not have a radiative zone. From 0.3 to 1.2 solar masses, the region around the stellar core is a radiative zone, separated from the overlying convection zone by the [[tachocline]]. The radius of the radiative zone increases [[Monotonic function|monotonically]] with mass, with stars around 1.2 solar masses being almost entirely radiative. Above 1.2 solar masses, the core region becomes a convection zone and the overlying region is a radiative zone, with the amount of mass within the convective zone increasing with the mass of the star.<ref name=padmanabhan2001/>
