SN 2016gkg

SN 2016gkg是位於螺旋星系NGC 613的一顆IIb型超新星[1]。它在2016年9月20日被業餘天文學家Víctor Buso在阿根廷聖大非省羅薩里奧自宅測試新購的相機時發現,因而成為第一位且是唯一的一位拍到超新星誕生照片的人,這將讓天文學家可以驗證解釋這種劇烈變化的理論[2]

"那天晚上,我要測試與練習如何使用剛買的一個有著更高解析力的相機。當我看到那個圖元,我害怕那是一個虛假的影像,因為當時它還不像超新星那樣的明亮,而且做為世界上唯一看見超新星誕生的人也令我驚恐。"

——Víctor Buso

這項研究的結果發表在科學雜誌《自然》上[3]

當Víctor Buso 拍攝到剛誕生的超新星時,他已經對宇宙進行了40年的掃瞄。

當我還只有十幾歲的時候,我就在基督國王學院的天文台發現了一顆變星,NSV 19555。然後,我們做了一個專案,以在南十字座找到更多的變星。變星是一種在其物理結構中存在危機,並產生亮度變化的一種恆星。有很多的原因,會使它們隨著年齡的增長,發生的脈動變得越來越不穩定,進而使其它的恆星相形見拙[2]
