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. ...

. Comment on J0405+3803 . Our image contains a feature of 25 mJy at 14 mas E-NE from the brightest component. It is not visible in the Caltech-Jodrell (CJ) survey image at 5 GHz (Xu et al. 1995) obtained about 6 years earlier. The 1.6 GHz CJ image (Polatidis et al. 1995) does show an extended feature close to the position in question, but somewhat displaced toward west. VLBApls home page . Last modified: 16 Oct 2000
