WebStars with spectral type M0, M1, M2 and M3, are much more safe. Stars with spectral types fainter than M4 (M5, M6, M7 and below) will be more unstable. Stars that rotate faster will also have more flares. Since older stars rotate slower, it … O-type stars are classified by the relative strength of certain spectral lines. The key lines are the prominent He lines at 454.1 nm and 420.0 nm, which vary from very weak at O9.5 to very strong in O2–O7, and the He lines at 447.1 nm and 402.6 nm, which vary from absent in O2/3 to prominent in O9.5. The O7 class … Ver mais An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers. They have temperatures in excess of 30,000 kelvin (K).
