WebClass B stars are extremely luminous and blue. Their spectra have neutral helium, which are most prominent at the B2 subclass, and moderate hydrogen lines. Ionized metal lines include Mg II and Si II. As O and B stars are so powerful, they only live for a very short time, and thus they do not stray far from the area in which they were formed. These stars tend … WebColor: Surface Temperature (K) Principal Features: Examples: O: Bluish-white: 30,000-50,000+ Relatively few absorption lines.

WebElectrons in a hydrogen atom must be in one of the allowed energy levels. If an electron is in the first energy level, it must have exactly -13.6 eV of energy. If it is in the second energy level, it must have -3.4 eV of energy. An electron in a hydrogen atom cannot have -9 eV, -8 eV or any other value in between. WebThe strongest lines are those of ionized helium. Lines of ionized calcium are the strongest in the spectrum; hydrogen lines show only moderate strength; lines of neutral and metals are present. The strongest lines are those of neutral metals and bands of titanium oxide. 20: Look at the chemical elements in Appendix K.
