Warmly dressed in glowing furs, this native of the planet Chillout III worships the dying light of his Sun, a Blue Dwarf Star in a galaxy far from our Milky Way. Threatened by global cooling, he dreams of a better life on a planet where there is increasing warmth…
Created in Apophysis 7x v14 following this tutorial in the Apophysis Tutorial Fun group. Rendered as a .png file, then blended with duplicate layers and a black background, mirrored and color adjusted with added supernova in GIMP v2.6, then saved in .jpg format, and finally scaled up in UF. Number 6 in a series of images generated with the instructions in the tutorial called Comprehensive Gnarls by dA’s Drummerboy08. Best if viewed larger.
Blue dwarf (red-dwarf stage)
From Wikipedia, the free encyclopedia
A blue dwarf is a hypothetical class of star that develops from a red dwarf star after it has exhausted much of its hydrogen fuel supply. Since red dwarf stars fuse their hydrogen slowly and are fully convective (allowing a larger percentage of their total hydrogen supply to be fused), the universe is currently not old enough for any blue dwarfs to have formed yet. Their existence is predicted based on theoretical models.1
Stars increase in luminosity as they age, and a more luminous star needs to radiate energy faster to maintain equilibrium. Stars larger than red dwarfs do by increasing their size and becoming red giants with larger surface areas. Rather than expanding, however, red dwarfs are predicted to increase their radiative rate by increasing their surface temperatures and becoming “bluer”. This is because the surface layers of red dwarfs do not become significantly more opaque with increasing temperature.
Blue dwarfs eventually evolve into white dwarfs once their hydrogen fuel is completely exhausted.
