Stellar survivor from 1572 A.D. explosion supports supernova theory

A new discovery by Pilar Ruiz-Lapuente and colleagues identifies a clear path for Type Ia supernovae to form in binary star systems. The research found that the companion star is similar to our sun, but slightly older and with high heavy-element content, supporting the theory that Type Ia supernovae originate from these systems.
