论文摘要

我们表明,常见的包络喷射超新星(CEJSN)R-PROCESS方案与最新的恒星在Ultra弱矮(UFD)Galaxy网状II中的最新观察确定的特性兼容,这些特性在R-Process元素中大大增强。这些新的结果,例如网状II星系中R过程的有效混合,对UFD星系的CEJSN R-Process方案具有一些影响。特别是,能量喷气机有效地与公共包膜弹射器混合在一起,然后将其与整个网状介质II有效混合。我们在场景和新观察结果之间发现的兼容性表明,CEJSN R-Process方案提供了R-Process元素的不可忽略的部分。

We show that the common envelope jets supernova (CEJSN) r-process scenario is compatible with very recent observationally determined properties of the stars in the ultra faint dwarf (UFD) galaxy Reticulum II that are strongly enhanced in r-process elements. These new results, like efficient mixing of the r-process elements in the Reticulum II galaxy, have some implications on the CEJSN r-process scenario for UFD galaxies. In particular, the energetic jets efficiently mix with the common envelope ejecta and then with the entire interstellar medium of Reticulum II. The compatibility that we find between the scenario and new observations suggests that the CEJSN r-process scenario supplies a non-negligible fraction of the r-process elements.
