This artist's impression shows a binary system containing a stellar-mass black h*** called IGR J17091-3624, or IGR J17091 for short. The strong gravity of the black h***, on the left, is pulling gas away from a companion star on the right. This gas forms a disk of hot gas around the black h***, and the wind is driven off this disk.
New observations with NASA's Chandra X-ray Observatory clocked the fastest wind ever seen blowing off a disk around this stellar-mass black h***. Stellar-mass black holes are born when extremely massive stars collapse and typically weigh between five and 10 times the mass of the Sun.
The record-breaking wind is moving about twenty million miles per hour, or about three percent the speed of light. This is nearly ten times faster than had ever been seen from a stellar-mass black h***, and matches some of the fastest winds generated by supermassive black holes, objects millions or billions of times more massive.
Another unanticipated finding is that the wind, which comes from a disk of gas surrounding the black h***, may be carrying away much more material than the black h*** is capturing.
The high speed for the wind was estimated from a spectrum made by Chandra in 2011. A spectrum shows how intense the X-rays are at different energies. Ions emit and absorb distinct features in spectra, which allow scientists to monitor them and their behavior. A Chandra spectrum of iron ions made two months earlier showed no evidence of the high-speed wind, meaning the wind likely turns on and off over time.
