Cygni is a star system in the Cygnus constellation. The primary star, Cygni A, is a blue-white star with a temperature around 19,000 K. The companion star, Cygni B, is a yellow-white star with a temperature around 8,500 K.
The temperature of Cygni, or specifically the star Deneb (also known as Alpha Cygni), is estimated to be around 8,500 Kelvin. This makes it a very hot and luminous star compared to our Sun, which has a surface temperature of about 5,500 Kelvin.
Chi Cygni is a variable star with a wide range of temperatures. It can vary from around 3,000 to 4,500 degrees Celsius based on its evolutionary stage and current activity.
There is no such star. Any of the major stars in the constellation Cygnus has "cygni" as part of its name - this is simply a suffix that means "of the Cygnus constellation".
Something is missing from your question. Cygni is not a star. The constellation name is Cygnus. The star will have a name like Alpha Cygni or 25 Cygni.
There is no star with the "F Cygni" classification since there is no exact Greek letter correlation.Zeta Cygni A is an expanding star with three times the mass of the Sun and 15 times its radius, and radiating at 112 times the Sun's brightness. It is fusing helium and has a surface temperature of about 4910 K (compared to 5778 K for the Sun).Gamma Cygni (Γ Cygni, aka Sadr) is an even larger star, a supergiant, 12 times the Sun's mass, 150 times its radius, and emitting 33,000 times as much energy. Its surface is only 6100 K, close to the Sun's 5778 K but with a much faster rate of change. It may only last a few million years in its current state.
