Astronomy characteristics of the resulting star depend primarily upon its starting mass. The more massive the star, the greater its luminosity, and the more rapidly it fuses its hydrogen fuel into helium in its core. Over time, this hydrogen fuel is completely converted into helium, and the star begins to evolve. The fusion of helium requires a higher core temperature. A star with a high enough core temperature will push its outer layers outward while increasing its core density. The resulting red giant formed by the expanding outer layers enjoys a brief life span, before the helium fuel in the core
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
