Gamma Hydrae is a third magnitude star in the constellation Hydra.
It has a spectral type of G8 which means it is a yellow giant falling off the main sequence.
Gamma Piscium is a star in the zodiac constellation of PiscesIt has a spectral type of G9 so it has a temperature of the lower 5,200--6,000 KIt is a yellow dwarf, similar to our own Sun.
Alpha Hydrae (Alphard) is a red giant star located in the constellation Hydra. It has a diameter that is estimated to be around 50 times that of the Sun.

Gienah is a blue-white giant star located in the constellation Cygnus. It is known as Gamma Cygni and is classified as a spectral type B8. The star is relatively young in its evolutionary stage and is around 1700 light years away from Earth.
The surface temperature of the star Gamma Pyxidis, a B-type main-sequence star, is approximately 20,000 to 25,000 Kelvin. This high temperature gives it a blue hue and contributes to its classification as a hot star. Its significant temperature also results in a substantial luminosity, making it one of the brighter stars in its region.
Alphard is the brightest star in the constellation Hydra.It's designation or letter is Alpha Hydrae
Gamma Draconis, also known as Eltanin, is an orange giant star. It has a spectral type of K5III, indicating its orange hue and giant status.
the gamma star is about 4000 times bigger than the sun
Gamma Cancri (Asellus Borealis) is a star system in the constellation Cancer.It is a star system and any size cannot be determined

gamma cephei (errai)
You would look for high-energy electromagnetic radiation like gamma rays emitted from the star. This type of radiation is produced during nuclear fusion reactions when light atomic nuclei combine to form heavier nuclei and release energy. Detection of gamma rays can provide evidence that nuclear fusion is taking place in the core of a star.
Sigma and Hydrae
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
The distance from Earth to the star Gamma Virginis, also known as Porrima, is approximately 38.2 light-years. This star is a binary star system located in the constellation Virgo.
Well it won't be soon but the star Gamma Cephie (Alrai) will become the north star in about 3000 CE
Gamma Draconis (Eltanin and Etamin) is a star in the constellation Draco.It is an orange giant of spectral type K5
