Webb1 juli 2024 · Spectral classes were soon arranged according to temperature and had letter designations in a sequence that went from hot to cool in the order — O, B, A, F, G, K and M. Type O stars have the highest surface temperatures that can be as hot as 30,000 Kelvins and Type M stars can be as cool as 3,000 Kelvins. Webb19 aug. 2024 · The coolest stars are red with surface temperatures of about 3,000ºC. As a star’s temperature increases, as a result of there being more gas in the star – and hence more fuel to burn – it becomes hotter. Its colour changes from orange, through yellow, to white. The hottest stars are blue, with temperatures up to 40,000ºC.
WebbThe hottest star we know of is WR 102, which is 210,000 degrees Kelvin, and that is much, much hotter than my predicted O0 temperature. So the short answer is yes, O0 temperature stars exist, but O0 isn't truly a real classification. (The hottest real classification is O2, at 53,000 Kelvin and up) Hope I helped! WebbThese stars range from hot, O- and B-type, blue objects at least 10,000 times brighter than the Sun down through white A-type stars such as Sirius to orange K-type stars such as …

The modern classification system is known as the Morgan–Keenan (MK) classification. Each star is assigned a spectral class (from the older Harvard spectral classification, which did not include luminosity ) and a luminosity class using Roman numerals as explained below, forming the star's spectral type.
