The fastest star in the galaxy propelled by thermonuclear supernova

Webb29 juni 2024 · A thermonuclear supernova is the explosion of a white dwarf star after it gains matter in a binary star system. An iron core-collapse supernova occurs when a massive star—one more than about ten times the sun’s mass—runs out of nuclear fuel, and its iron core collapses, creating a black hole or neutron star. WebbAll supernovae are produced via one of two different explosion mechanisms.

WebbAs a result, these primordial AGB stars could have experienced a carbon deflagration, ending their lives as type I and 1/2 supernovae, i.e, thermonuclear supernovae, such as type Ia, but showing H in their spectra, such as type II. Later on, this scenario for metal-deficient AGB stars was substantially revised [11,17,25,26].
