Stellar evolution fully convective and will not develop a degenerate helium core with a shell burning hydrogen. Instead, hydrogen fusion will proceed until almost the whole star is helium. Slightly more massive stars do expand into red giants, but their helium cores are not massive enough to reach the temperatures required for helium fusion so they never reach the tip of the red giant branch. When hydrogen shell burning finishes, these stars move directly off the red giant branch like a post-asymptotic-giant-branch (AGB) star, but at lower luminosity, to become a white dwarf. A star with an initial mass above about will
Red and white giant flying squirrel Red and white giant flying squirrel The red and white giant flying squirrel ("Petaurista alborufus") is a species of rodent in the family Sciuridae. It is the largest species of giant squirrel and has blue eyes. It is also known as the Chinese giant flying squirrel. At over a meter long including its tail, the red and white giant flying squirrel is the largest of its kind. Endemic to central and southern China and Taiwan, they inhabit dense hillside forests in mountainous terrain. They spend their days sleeping, emerging after sundown to forage in the trees. Their diet consists primarily
