This paper presents an intelligent system for the classification of low-resolution optical spectra of the stars in the current standard MK system. We propose a comparative analysis of two techniques, artificial neural networks and statistical clustering algorithms, applied to the spectral classification ...

Blue stars are also often found in complex multi-star systems, where their evolution is much more difficult to predict due to the phenomenon of mass transfer between stars, as well as the possibility of different stars in the system ending their lives as supernovas at different times. Blue s...
fall between red M-type main-sequence stars and yellow G-type main-sequence stars. K-type stars are of particular interest inthe search for extraterrestrial life, since they emit markedly less UV radiation (that damages or destroys DNA) than G-type stars on the one hand, and they remain st...

The modern system of stellar classification is that of Morgan–Keenan (MK). The MK system is set up to be independent from theoretical considerations regarding the physics of stellar atmospheres. Each spectral type is assigned in comparison to adopted standard stars. In this way, a star of, sa...
