Stellar Classification | Research Starters | EBSCO Research Stars are usually classified into one of seven temperature-based types: O, B, A, F, G, K, or M Following that initial classification, stars are given a second classification to denote their current life-cycle phase Astronomers classify stars according to their mass and temperature
Looking Stellar: How We Classify Stars | Museum of Science The first person to attempt to create a systematic way of classifying stars based on their spectra was a guy named Angelo Secchi in the 1860s He focused primarily (though not exclusively) on stars’ hydrogen lines to divvy them up into five classes marked by Roman numerals Of course Secchi was just eyeballing the stars’ spectra one at a time
