Let’s Blow Up a Star!Almost a decade ago, amongst the heap of exotic transients observed every day in our Universe, a new class of stellar explosion was identified and labeled Type Iax supernovae (SNe Iax). Similar to the infamous Type Ia supernovae (SNe Ia) that are commonly used to measure the expansion rate of the universe, SNe Iax are also thought to arise from the destruction of a white dwarf star as it approaches the Chandrasekhar mass limit. However, these supernovae are physically distinct explosions from SNe Ia given their low observed luminosities and kinetic energies, combined with the slow velocities at which the obliterated ...
