RUI: An Observational Study of Post-AGB Transitional Objects

虽然低质量和中质量恒星演化的大多数阶段都有很好的记录，但从红巨星到行星状星云的转变仍然很少被观察到。这是由于这一阶段的短暂，恒星经常被尘埃遮蔽，而且很难识别这些物体。目前已确定了55名候选人，将对其进行观察，以核实其身份并确定其属性。

9315107 Hrivnak While most phases in the evolution of low and medium mass stars are well documented, the transition from red giants to planetary nebulae remains poorly observed. This results from the briefness of this stage, the fact that the stars are often obscured in dust and the difficulty of identifying such objects. Fifty-five candidates have now been identified and will be observed to verify their status and determine their properties.
