If the progenitor star was 8 to 10 times the Sun’s mass, what elements typically compose the resulting white dwarf?
Answer
Oxygen, neon, and magnesium (O/Ne/Mg)
While most white dwarfs are composed of carbon and oxygen, those originating from more massive progenitor stars (around 8 to 10 solar masses) will be composed primarily of oxygen, neon, and magnesium.
