A.
GK Persei
GK Persei is a well-known cataclysmic variable star and classical nova in the constellation Perseus, famous for its dramatic 1901 nova outburst and expanding nebular remnant.
-
B.
B Cassiopeiae
B Cassiopeiae is the historic supernova observed in 1572 in the constellation Cassiopeia, famously studied by Tycho Brahe and crucial to early modern astronomy.
-
C.
Gamma Cassiopeiae
Gamma Cassiopeiae is a bright, variable Be-type star in the constellation Cassiopeia, known for its rapid rotation, circumstellar disk, and irregular outbursts.
-
D.
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.
-
E.
Cassiopeia A
Cassiopeia A is a well-studied, relatively young supernova remnant in the constellation Cassiopeia and one of the strongest radio and X-ray sources in the sky.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
