Astronomers usually thought that the neutron stars are less bright as compared to the other main stars of the Universe.
This theory is proved wrong with the latest research done by Dr. Sylvain Chaty of the University Paris 7.
The research has led to the discovery of neutron stars that are orbiting inside a cocoon of cold gas and dust that hides a supergiant star.
The cocoon is so dense that it absorbs all the energy that is emitted from these stars making them invisible to normal telescopes.
The result was obtained using multi-wavelength observations that were conducted using the European International Gamma-Ray Astrophysics Laboratory satellite. Twenty such binary systems have been found that are at a distance of 7,000 to 25,000 light years, this means that they are well inside our own milky way.
Scientists have also commented that most of these sources are made up of a compact object orbiting a supergiant star that is 30 times the mass of sun and 20 times its diameter.
Such stars are so unstable that they eject a huge amount of cold gas and dust. This ejected amount is so large that if we compare it to the sun, then the whole mass of the sun will be ejected in just 100,000 years. The compact or the neutron star is a highly dense object that is about 1.4 solar masses and just 10 kilometers in diameter. Such a neutron star is also high in emitting X-Rays. But due to the density of the gas cocoon that is surrounding the neutron star it remains invisible to the normal telescopes.
Researchers have also stated that the findings will help them to understand the evolution and fate of such massive stars in high energy binary systems.
