论文摘要
人们认为太阳是在星团内形成的。 $^{26} {\ rm al} $的共存性和$^{26} {\ rm al} $ - 可怜的钙 - 钙 - 富含铝 - 铝含量的夹杂物直接注入$^{26} {\ rm al} $的共存,应该从附近的core core core core colle-collape colle-collape of $ collape of $ collape use prived $ $ collape use prived $ $ collape of $ $。因此,在太阳的出生簇中,至少应该在恒星形成的持续时间内发生至少一个核心溢出的超新星。在这里,我们从在出生集群中恒星形成的有限持续时间内获取至少一个核心折叠超新星的概率的角度来重新审视太阳的出生簇中的恒星数量。我们发现,根据恒星形成的持续时间,出生簇中的恒星数量可能明显大于先前所考虑的恒星数量。
The Sun is thought to be formed within a star cluster. The coexistence of $^{26}{\rm Al}$-rich and $^{26}{\rm Al}$-poor calcium--aluminum-rich inclusions indicates that a direct injection of $^{26}{\rm Al}$-rich materials from a nearby core-collapse supernova should occur in the first $10^5$ years of the solar system. Therefore, at least one core-collapse supernova should occur within the duration of star formation in the Sun's birth cluster. Here we revisit the number of stars in the Sun's birth cluster from the point of view of the probability for acquiring at least one core-collapse supernova within the finite duration of star formation in the birth cluster. We find that the number of stars in the birth cluster can be significantly larger than that previously considered, depending on the duration of star formation.
