英文摘要We present that supernovae interacting with a dense Si-and S-rich circumstellar matter like SN 2021yfj can originate from mergers of two white dwarfs. A C + O white dwarf accreting He from its non-degenerate He companion star can initiate a C-burning frame at its surface propagating inward under certain conditions. Such a burning frame synthesizes intermediate-mass elements such as Si and S, forming a hybrid white dwarf with an outer Si + S-rich layer. After the He star companion becomes a white dwarf, the two white dwarfs can eventually merge. During the merger, the outer layers of the hybrid white dwarf can be tidally stripped, forming a dense Si-and S-rich circumstellar matter. If a thermonuclear explosion is triggered in the merging white dwarfs, an explosion within a dense Si-and S-rich circumstellar matter can be realized, resulting in SN 2021yfj-like events. We argue that the properties of SN 2021yfj can be reproduced by a dense Si-and S-rich circumstellar matter having similar or equal to 0.3 M-circle dot within which an explosion with kinetic energy of similar or equal to 4 & times; 10(50) erg and ejecta mass of similar or equal to 0.3 M-circle dot occurred. These properties are consistent with the double white dwarf merger scenario. This scenario can naturally explain the existence of He observed in SN 2021yfj. Because white dwarf mergers can also lead to the formation of He and C + O dense circumstellar matter, some Type Ibn and Icn supernovae may also originate from a similar evolutionary path.
