NGC 1501是一个复杂的行星状星云，威廉·赫歇尔于1787年8月27日在鹿豹座这个星座内发现它^[2]^[3]。它也被称为牡蛎星云^[4]。

性质

行星状星云的中心恒星的光谱类型为[WC4]，类似于富含碳的沃夫–瑞叶星^[5]。它是一颗脉动的恒星，这意味着它的亮度有规律地和周期性地变化。就NGC 1501的前身恒星而言，这是非常快的，恒星的亮度在短短半小时内发生了显著变化。分析盖亚的数据表明，中央恒星是一个联星系统^[6]。可见光观测捕捉到包括氢气和氮气在内的气体辉光^[7]。星云的总质量估计约为0.22 M_☉，其中大部分是电离气体（0.21 M_☉）和一小部分（6996890000000000000♠8.9×10⁻⁴ M_☉）是富含碳的灰尘^[8]。
