black hole, white dwarf

Intrepid white dwarf has a close encounter with a massive black hole
Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be coming from a white dwarf - a highly compact stellar ember - with a death wish.
Astronomers Found Strange, Accelerating X-Ray Pulses Coming From a Black Hole. They Might Be a Sign of an Orbiting White Dwarf
The dense stellar remnant would, if confirmed, be the closest known object to any black hole, according to preliminary research
Supermassive black hole births jets, hosts orbiting white dwarf, all while astronomers watch
Since 2018, we've seen 1ES 1927+654 generate jets in real time and found it may have a lone white dwarf orbiting near the point of no return.
'Daredevil' white dwarf star could be closest-known object to a weird black hole
The weird outbursts of a distant supermassive black hole may be caused by a death-defying white dwarf walking a cosmic tight rope around it.
Mysterious flashing seen near supermassive black hole. Astronomers have an idea what it is
A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?
Mysterious black hole starts flashing – and scientists don’t know why
A mysterious black hole has started behaving even more strangely, scientists have said. The supermassive black hole has been sending out flashes that have increased in speed. The black hole is known as 1ES 1927+654,
Mysterious flashes from a distant black hole puzzles astronomers
Astronomers have observed strange behaviors in a distant black hole. Plasma jets are moving fast, and X-ray flashes are increasing in frequency. They suspect a white dwarf is orbiting close to the black hole's event horizon.
Mysterious x-ray flashes are accelerating in a black hole
Astronomers detected X-ray flashes from the black hole that increased in frequency from one every 18 minutes to one every seven minutes.
A supermassive black hole is sending out a mysterious pulsing beat
Regular pulses of X-ray radiation emanating from a supermassive black hole could be explained by a white dwarf star on the verge of falling in
Astronomers detect rare X-ray flares from black hole 1ES 1927+654 caused by a nearby white dwarf
The observations revealed features never before seen in real time around a supermassive black hole. Among them was the launch of a plasma jet moving at nearly one-third the speed of light.
