NGC 1501是一個複雜的行星狀星雲，威廉·赫歇爾於1787年8月27日在鹿豹座這個星座內發現它^[2]^[3]。它也被稱為牡蠣星雲^[4]。

性質

行星狀星雲的中心恆星的光譜類型為[WC4]，類似於富含碳的沃夫–瑞葉星^[5]。它是一顆脈動的恆星，這意味著它的亮度有規律地和週期性地變化。就NGC 1501的前身恆星而言，這是非常快的，恆星的亮度在短短半小時內發生了顯著變化。分析蓋亞的數據表明，中央恆星是一個聯星系統^[6]。可見光觀測捕捉到包括氫氣和氮氣在內的氣體輝光^[7]。星雲的總質量估計約為0.22 M_☉，其中大部分是電離氣體（0.21 M_☉）和一小部分（6996890000000000000♠8.9×10⁻⁴ M_☉）是富含碳的灰塵^[8]。
