High energy systems in gas cocoons
Because their large quantity of X-Rays absorption by cocoon, those stars couldn't be discover until the 5 of this month, using the European "International Gamma-Ray Astrophysics Laboratory" satellite.
Those kind of systems are formed by 2 stars.
Have been found 20 systems from 7.000 to 25.000 years light from Earth.
Neutron stars from those systems are 20 times larger as diameter comparing with the Sun and with a mass of 30 times bigger.
