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.

9315107 Hrivnak虽然低质量和中等质量恒星演化的大部分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简单性、恒星经常被尘埃遮挡以及识别此类物体的难度造成的。现在已经确定了55名候选人，将对他们进行观察，以核实他们的身份并确定他们的财产。
