What elements do sirius star fused?

Answer 1

Sirius, primarily composed of a main-sequence star known as Sirius A, predominantly fuses hydrogen into helium in its core. As a more massive star, it may eventually undergo further fusion processes, creating heavier elements like carbon and oxygen as it evolves. Sirius B, the white dwarf companion, is the remnant of a star that has completed its fusion processes and primarily consists of carbon and oxygen.
