Carbon star
A carbon star is a luminous type of red giant that has a carbon-rich atmosphere. When carbon stars like CW Leonis run out of hydrogen fuel in their cores, the ability to balance their own gravity and outward pressure disappears, and they start to erupt and collapse. The orange glow emitting from CW Leonis is the superhot carbon-rich dust surrounding it, which is being tossed away from the collapsing core.
