Scientists have discovered that the debris left over from a star that was torn apart by a supermassive black hole is now impacting another star or smaller black hole orbiting the giant one.
In 2019, ground-based observatories found a black hole shredding a star in an event called AT2019qiz. In late 2023, our Chandra X-ray Observatory detected an X-ray flare from this object. Intensive monitoring with our NICER telescope revealed that such eruptions are occurring about every 48 hours, which was then confirmed by our Swift observatory and India's AstroSat telescope.Then, thanks to data from Chandra and NASA's Hubble Space Telescope, astronomers found that the disk of debris from that original star had expanded enough that if an object was orbiting the black hole on timescales of a week or less, it would now be colliding with the disk, causing the eruptions.
