-
D.
Cygnus X-3
Cygnus X-3 is a powerful X-ray binary system in the constellation Cygnus, believed to consist of a compact object such as a black hole or neutron star orbiting a massive companion star and known for its intense X-ray and gamma-ray emissions.
-
E.
Cygnus X-2
Cygnus X-2 is a bright low-mass X-ray binary system in the constellation Cygnus, consisting of a neutron star accreting matter from a companion star and serving as an important source for studying X-ray emission and compact objects.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
