text: If the mass of a white dwarf increases above 1.4 solar mass (Chandrasekhar mass limit), for example due to mass transfer from the companion star in a binary, or when the temperature rises just enough to start nuclear fusion in the core material, the whole star explodes in a fraction of a second as a supernova, leaving behind an expanding nebula.
