模型被用来探索ONeMg核心，这是从恒星的质量范围在8和10之间的太阳质量的演化结果的爆炸点火的结果。论证表明，热核超新星生产或“铁”矮星形成较温和的爆发是ONeMg核心爆炸点火的可能结果。ONeMg核爆炸点火的物理机制很可能是超新星Ia和超新星Ib/c爆发等现象的关键，也可能是一种新的天体类型的关键。参考文献21篇。
Models are used to explore the outcome of explosive ignition of ONeMg cores, which result from the evolution of stars in a mass range between 8 and 10 solar masses. Arguments are presented showing that the thermonuclear supernova production or the 'iron' dwarf formation by milder outbursts are possibile outcomes of the explosive ignition of ONeMg cores. It is suggested that the physics of the explosive ignition of ONeMg cores may well be a key to such phenomena as SN Ia and SN Ib/c outbursts, or perhaps to a new type of objects. 21 refs.
