Zwitter, Tomaž; Traven, Gregor; Gilmore, Gerry +13 more

Binaries have received much attention as possible progenitors of type Ia supernova explosions¹, but long-term gravitational effects^2,3 in tight triple or quadruple systems could also play a key role in producing type Ia supernovae. Here we report on the properties of a spectroscopic quadruple found within a star cluster: the …
