Will Earth survive when the sun becomes a red giant?

WebThe Sun and the red giant branch stars (hereafter RGBs) have very different surface conditions. A red giant surface gravity and energy flux are much smaller than the solar ones. The purpose of the work we present is to check how this changes the surface convection efficiency. First we build calibrated solar models using the mixing length theory ...

WebRed Giant Branch: When the star leaves the main sequence, it enters the red giant branch, where it is burning helium in the core and hydrogen in a shell outside. The helium burning expands the core, and therefore cools the hydrogen burning shell. The star increases in luminosity (becomes brighter), and cools slightly as it expands (becomes redder).
