This Black Hole Keeps Biting From A White Dwarf In Its Orbit

According to recent reports, an astronomer believes that he spotted a stellar corpse known as a white dwarf that’s sending out blazes of light – these are a sort of mayday signals from the close orbit of a black hole.

Such a white dwarf is a result of a star that’s naturally running out of fuel and exploding, experts believe that the black hole snatched all of a red giant’s free gas away. This reportedly triggered the premature death.

“In my interpretation of the X-ray data, the white dwarf survived, but it did not escape,” Andrew King stated.

He is the author of the new research and an astrophysicist at the University of Leicester in the U.K., said in a NASA statement.

He continued and explained, “It is now caught in an elliptical orbit around the black hole, making one trip around about once every nine hours.”

Indiagoneviral reports that King’s new research is based on observations that have been gathered by NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton X-ray telescope.

These have been focused on the drama unfolding in a galaxy called GSN 069 – this is located about 250 million light-years away from Earth.

Near-miss tidal disruption event

It’s been revealed that every nine hours, the galaxy is experiencing a spike in X-ray emissions. by analyzing these spikes, King came up with a theory of a so-called “near-miss tidal disruption event.”

Experts have studied lots of tidal disruption events, in which a black hole is tearing apart a star that comes too close.

It seems that when a red giant came too close to the black hole, it snatched away all of its hydrogen and it left the core white dwarf behind.

More than that, the black hole could not finish the job, and it trapped the white dwarf in a nine-hour elongated orbit.
