Шаблон:Short description Шаблон:Lowercase Шаблон:Infobox supernova iPTF14atg is a type-Ia supernova discovered on 3 May 2015. The supernova is located in galaxy IC 831, some Шаблон:Convert distant.[1] The supernova is thought to have ignited on May 2 or 3.[2] The supernova's shockwave slammed into a companion star, shocking it into producing an ultraviolet pulse.[3] The companion star that was hit is suspected to be a red giant star.Шаблон:Cn This detection of the UV signal represents the first time the collision event of a supernova shockwave upon a companion star has been detected.[4] The supernova was discovered by the Intermediate Palomar Transient Factory (iPTF), a successor to the earlier Palomar Transient Factory, and based at the Palomar Observatory in California. The data was processed by collaborators in Europe, that lead to the supernova discovery.[3]
This single-degenerate white dwarf with normal star binary system represents one of two mechanisms for producing a type-Ia supernova, the other being double-degenerate two white dwarf binary stars.[1][4]
