==概要==<br />
由兩顆O型恆星組成的VFTS 352聯星系統是由[[欧洲南方天文台]]的[[甚大望远镜]]發現的<ref name='A Now'>{{cite news |url=http://astronomynow.com/2015/10/21/final-kiss-of-two-stars-heading-for-catastrophe/ |title=Final kiss of two stars heading for catastrophe |work=Astronomy Now |date=21 October 2015 |accessdate=2015-10-21 |archive-date=2015-10-22 |archive-url=https://web.archive.org/web/20151022144758/http://astronomynow.com/2015/10/21/final-kiss-of-two-stars-heading-for-catastrophe/ |dead-url=yes }}</ref>，並且相關文章於2015年10月13日發表<ref name="Almeida 2015"/>。VFTS 352是由兩顆體積相當，並且表面溫度達到 40,000°C 的高溫明亮巨星組成。兩顆恆星互相環繞的軌道週期稍長於一日，並且因為極為靠近，兩顆恆星的表面已經相互連接<ref name='A Now'/>。如同VFTS 352這樣極端狀況的恆星被認為內部核融合反應主要產物為氧等元素<ref name='A Now'/>。<br />
<br />
目前仍無法確認 VFTS 352 未來演化結果，只能推測兩種可能狀況。如果兩顆恆星合併，將形成一顆自轉速度極高的恆星。如果合併後的新恆星仍保持高速自轉，將以長時間的[[伽玛射线暴]]結束生命。第二種狀況則可能是[[超新星]]爆炸後形成距離極為接近的雙黑洞，並且兩個黑洞合併時可能會產生[[重力波 (相對論)|重力波]]<ref name="Reilly 2015">{{cite news |last=Reilly |first=Rachel |url=http://www.dailymail.co.uk/sciencetech/article-3282992/The-kiss-DEATH-Hottest-largest-double-star-discovered-form-black-holes.html |title=The kiss of Death: Hottest and largest ever double star system discovered - and it could be about to form a black hole |work=Daily Mail |location=UK |date=21 October 2015 |accessdate=2015-10-21 |archive-date=2015-10-21 |archive-url=https://web.archive.org/web/20151021221440/http://www.dailymail.co.uk/sciencetech/article-3282992/The-kiss-DEATH-Hottest-largest-double-star-discovered-form-black-holes.html }}</ref><ref name="Almeida 2015"/>。<br />
