The coolest layer on the Solar is usually a temperature bare minimum region extending to about 500 km earlier mentioned the photosphere, and has a temperature of about 4,100 K.[seventy seven] This part of the Sunlight is cool more than enough to allow for that existence of simple molecules for example carbon monoxide and h2o, which can be detected by means of their absorption spectra.
[a hundred and forty] The Sunlight then shrinks to around 10 times its present sizing and fifty times the luminosity, having a temperature slightly lower than right now. It will eventually then have attained the pink clump or horizontal branch, but a star with the Solar's metallicity will not evolve blueward together the horizontal branch.
