本文探讨红巨星分支阶段发生的共包层事件能否形成行星状星云，并指出已有理论与观测证据支持这一可能性，强调表征此类系统有助于揭示共包层这一关键演化阶段。

摘要：

自四十五余年前提出以来，共包层事件一直与行星状星云的形成联系在一起。然而，直到最近，人们仍存有疑问：当供体星正处于上升的红巨星分支阶段，而非随后的渐近巨星分支阶段时，共包层过程是否会产生行星状星云。目前已有强有力的理论和观测证据表明，一些行星状星云确实是共包层阶段的产物，而这些共包层阶段发生在星云前身天体位于红巨星分支之时。对这些系统的表征具有挑战性，但有可能揭示大量关于共包层的信息——共包层是众多有趣天体物理现象形成过程中的一个关键演化阶段。

英文摘要：

Common envelope events have been associated with the formation of a planetary nebulae since its proposition more than forty five years ago. However, until recently there have been doubts as to whether a common envelope while the donor is ascending the red giant branch, rather than the subsequent asymptotic red giant branch, would result in a planetary nebula. There is now strong theoretical and observational evidence to suggest that some planetary nebulae are, indeed, the products of common envelope phases which occurred while the nebular progenitor was on the red giant branch. The characterisation of these systems is challenging but has the potential to reveal much about the common envelope -- a critical evolutionary phase in the formation of a plethora of interesting astrophysical phenomena.
