Black Hole Found in Binary Star System: More Than Five Times Greater in Mass Than Our Sun

Researchers from the Instituto de Astrofisica de Canarias (IAC) have discovered the existence of a black hole 5.4 times greater in mass than that of our Sun, located in the X-ray binary system, stellar systems composed by a compact object and a 'normal' star. They then undergo the absorption process of accretion. They managed to obtain the first spectroscopic date from this binary system to be published.

Black holes are the remains left by a massive star after its death. Most of the known neutron stars have a mass around 1.4 times that of the Sun, though in some cases, values up to over twice the mass of the Sun have been measured. Astronomers believe that when greater than three times the solar mass, neutron stars are not stable, and end up collapsing and forming a black hole.

This is most likely what happened in the formation of this massive Black Hole

I found this article to be very surprising. When you think of how large our Sun is, it's hard to imagine an object that is 5.4 times greater in mass. It's also pretty cool how researchers were able to detect this massive black hole with it being located in the X-ray binary system. I feel like there are a lot of other massive objects out there and it will be interesting to see what they discover next.

I agree, this is very interesting. It is very hard to imagine something 5.4 times greater in mass than the sun. Black holes are also so fascinating. I wonder what this could lead to. I mean, think about how much this black hole is taking in. I am not very familiar with the X-ray binary system, but I wonder how this massive black hole is affecting the space and objects surrounding it.
