X9 astronomy

How far is X9 from Earth?
Astronomers found this extraordinarily close stellar pairing in the globular cluster named 47 Tucanae, a dense collection of stars located on the outskirts of the Milky Way galaxy, about 14,800 light years from Earth.
This particular source, known as X9, has been of interest to scientists for many years._{Mar 13, 2017}.
What is the closest black hole to Earth?
Data from the European Space Agency's (ESA) Gaia mission revealed the closest known - and second closest - black holes in 2022, Gaia BH1 and Gaia BH2, which are 1,560 light-years and 3,800 light-years from Earth respectively..

What star is closest to becoming a black hole?
The nearest star to us that could become a black hole during its evolution is probably Theta Orionis C, with a mass of about 40 times that of the Sun.
It is located about 1500 light-years away.
Orion's Trapezium Cluster.
Theta Orionis C is the brightest star in the lower corner of the cluster..
When was X9 discovered?
While astronomers have observed this extraordinary binary, called X9, for many years, it wasn't until 2015 that radio observations revealed the pair likely contains a black hole that pulls material from a companion star called a white dwarf, a low-mass star that has exhausted most or all of its nuclear fuel and has _{Mar 13, 2017}.

Which star turns into a black hole?
What kinds of stars end up as black holes? They are the natural consequence of the evolution of massive stars.
Neutron stars have an upper mass limit of 2 to 3 solar masses.
A collapsed object of greater mass will continue to collapse indefinitely, forming a black hole..
One Star's End is a Black Hole's Beginning
Most black holes form from the remnants of a large star that dies in a supernova explosion. (Smaller stars become dense neutron stars, which are not massive enough to trap light.)
S4716 is an S star located at the center of the Milky Way galaxy orbiting the supermassive blackhole Sgr A* at the speed of 8,000 kilometres per second in closest approach of 100 AU.
As of July 2022, the orbital period of S4716 was the shortest known of any star in the Milky Way galaxy.
Stars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors.
The outflow of energy from the central regions of the star provides the pressure necessary to keep the star from collapsing under its own weight, and the energy by which it shines.
The nearest star to us that could become a black hole during its evolution is probably Theta Orionis C, with a mass of about 40 times that of the Sun.
It is located about 1500 light-years away.
Orion's Trapezium Cluster.
Theta Orionis C is the brightest star in the lower corner of the cluster.
When they run out of material to fuse in their cores, these stars destabilize, and eject all their outer material.
The stellar core, no longer supported by the outward pressure of fusion, collapses under gravity into a white dwarf.

Mar 13, 2017This particular source, known as X9, has been of interest to scientists for many years.
Until a couple of years ago, astronomers thought X9 ,Mar 13, 2017Until a couple of years ago, astronomers thought X9 contained a white dwarf pulling material from a companion star like the Sun.
(Astronomers ,Astronomers found that the white dwarf in X9 completes one orbit around the black hole in less than a half an hour.
They estimate the white dwarf and black hole are separated by about 2.5 times the distance between the Earth and Moon — an extraordinarily small span in cosmic terms.,Astronomers found this extraordinarily close stellar pairing in the globular cluster named 47 Tucanae, a dense collection of stars located on the outskirts of the Milky Way galaxy, about 14,800 light years from Earth.

Using NASA's Chandra X-ray Observatory along with data from other telescopes, researchers determined that the white dwarf makes one complete orbit around the black hole in less than a half an hour.,While scientists have found this configuration many times before, this binary, known as X9, is special.
That's because it has the closest orbit ever seen between a black hole and a companion star.
