'''IGR J17091-3624'''（簡稱'''IGR J17091'''），是一個距離地球約2萬8千光年，銀河系內的[[恆星黑洞]]，位於[[天蠍座]]<ref>{{cite web|url=http://chandra.harvard.edu/photo/2012/igr/|title=IGR J17091: Chandra Finds Fastest Winds|publisher=''NASA/Harvard''|author=Ashley King|display-authors=et al.|accessdate=September 27, 2012|date=February 21, 2012|archive-date=2012-09-19|archive-url=https://web.archive.org/web/20120919093405/http://chandra.harvard.edu/photo/2012/igr/|dead-url=no}}</ref>。

==發現==
IGR J17091是由[[歐洲太空總署]]的[[国际伽玛射线天体物理实验室]]發現於2003年4月<ref>{{cite web|url=http://www.astronomerstelegram.org/?read=149|title=IGR J17091-3624|publisher=''astronomerstelegram.org''|author=Erik Kuulkers|accessdate=January 17, 2013|date=April 19, 2003|archive-date=2016-02-07|archive-url=https://web.archive.org/web/20160207102147/http://www.astronomerstelegram.org/?read=149|dead-url=no}}</ref>。

==概要==
IGR J17091是一顆位於聯星系統內，質量約3-10 [[太陽質量|<math>\begin{smallmatrix}M_\odot\end{smallmatrix}</math>]]的恆星黑洞<ref name="#1">{{cite web|url=http://chandra.harvard.edu/press/12_releases/press_022112.html|title=Chandra Finds Fastest Winds from Stellar Black Hole|publisher=''NASA''|author=Ashley King|display-authors=et al.|accessdate=September 27, 2012|date=February 21, 2012|archive-date=2013-01-07|archive-url=https://web.archive.org/web/20130107225459/http://chandra.harvard.edu/press/12_releases/press_022112.html|dead-url=yes}}</ref>。其質量讓它成為目前發現質量最小的黑洞，接近黑洞能穩定存在的質量下限<ref>{{cite web|url=http://www.space.com/15941-strangest-black-holes-universe-countdown.html|title=Strangest Black Holes in the Universe, pg 9|publisher="Space.com"|author=Charles Q. Choi|accessdate=September 27, 2012|date=August 24, 2012|archive-date=2019-05-16|archive-url=https://web.archive.org/web/20190516144650/https://www.space.com/15941-strangest-black-holes-universe-countdown.html|dead-url=no}}</ref>。

[[钱德拉X射线天文台]]於2011年對該黑洞的觀測發現它的[[吸積盤]]的氣流速度達到光速的3%，是至今最高速度，遠高於第二高的紀錄。根據[[密歇根大学]]天文學家 Ashley King 所述，「和一般認為黑洞將周圍大多數的物質拉近的概念相反的是，我們認為IGR J17091周圍吸積盤內95%的物質被高速氣流吹離」<ref name="#1"/>。

IGR J17091的[[X射线]]變化模式也相當特殊。它的模式是振幅小、半週期，並且5到70秒之間就一次爆發<ref>{{cite journal |last=Rao |first=Anjali |last2=Vadawale |first2=S.
