The black hole. ... The black holes are generated in the result of a collapse of giant stars with the mass more than three Sun's masses. ... And moreover the gas near the neutron star or the black hole will get hot and will become a source of high energetic electromagnetic radiation in X-rays and gamma range. ... In the majority of double systems, being the sources of X-rays radiation, the invisible component mass does not exceed the two solar masses, so it is a neutron star. ...

... My mother had a 'star named for me' with the International Star Registry (henceforth ISR) as a gift for this Christmas. ... On the back of the chart, a sticker described the precise location and visual magnitude of the star, taken from the Hubble Guide Star Catalog. The first thing I noticed, was the chart was Epoch 1950. ... The coordinates were also exactly those on the ISR sticker, so I now knew that even though the ISR chart was epoch 1950, the coordinates on the sticker were epoch 1983. ...
