We have no way of predicting accurately where intelligent life can exist, we can only predict where human or earth-based life can exist. Life is a self-repeating chemical system, and it can potentially exist in any solar system, even on frozen moons that still have warm cores. Life that would be truly "alien" to us might even exist in the cold, seemingly dead space between stars, we can't know.

If you look at the Spectral classes of stars, you will see that this star is a medium sized Blue-white star(3-18 MSun, 95-52000 LSun, Spectral class B). The average main sequence lifespan of this type of star is, according to the table, is 11-400 million years.
The diagram was created by Ejnar Hertzsprung and Henry Norris Russell aound 1910.
There really are no stars in the film Climax 3 as it's a film that does not exist. Climax 3 is also not even a television show that exists so there is no one that stars in it.
Orion's Belt is made up of 3 main stars.From left to right as seen from Earth :-Zeta Orionis or Alnitak is a triple system of 2 blue supergiant stars of spectral type O9 and a smaller blue/white giant star of type B0 III. It is approx. 800 light years away.Epsilon Orionis or Alnilam is a blue/white supergiant star of spectral type B0 Iab. It is approx 1,300 light years from Earth.Deta Orionis or Mintaka is a binary system of a bright blue giant star of spectral type O.5 III and a blue/white star of type B2 V. It is approx. 900 light years from us.
Spectral class Y, which is typical of "brown dwarf" stars.
Spectral class is classification of stars by their external features..Like light,temperature etc..
There are stars with spectral classes of O & B (e.g. Rigel) R136a1 is a star of the spectral class WN5h. Wolf Rayet stars have this kind of spectral type.
temperature
Our Sun has a spectral class of G (Yellow dwarf). About 1 in 13 stars, in our solar neighbourhood are within this class
Spectral class is the categorization of stars by temperature and size, mostly the former. Spectral class B is very hot. In descending order (hottest to coolest) the spectral classes are O,B,A,F,G,K,M. You can see that B is very near the top.
Red stars (Red dwarfs and red giants) have a spectral class of M.
Red stars (Red dwarfs and red giants) have a spectral class of M.
Typically orange stars have a spectral class of K. Examples are:ArcturusAldebaranAlpha Centauri B
No. K spectral type stars (which are orange) temperature is ranging from 5,000-3,500. A spectral type stars (which are blue-white) temperature is ranging from 7,500-11,000.
A star with luminosity class VI under the Yerkes Spectral Classification System. They have luminosity 1.5 to 2 magnitudes lower than main-sequence stars of the same spectral type.
their surfaces are so cool that most hydrogen is in the ground state.
