A research group led by assistant professor Wu Chengyuan from Yunnan Observatories of the Chinese Academy of Sciences has investigated the evolution of post-merger remnant resulting from the coalescence of double oxygen-neon white dwarfs. They have found that the final fate of such remnant is impacted by the process of convective boundary mixing. However, the wind mass-loss process and rotation may not affect the evolution and final fate of the remnant too much.
