What specific observation allows scientists to trace the history of a dead star by analyzing its remnant?

Answer

The relative abundance of elements like silicon, sulfur, and argon

By studying the material ejected in the remnant gas, scientists can determine the mass and type of the star that died, as the relative abundance of elements reflects the fusion processes inside the star.
