O-type stars
WebAn O-type star ( O) is a star within the O-class , a spectral class indicating stars with ionized helium absorption lines, a blue color, and a surface temperature above 30,000 K. The spectral energy distribution (SED) peaks in the XEUV range. Main sequence stars of this class are on the order of 50 solar masses, 10 solar radii, and 100,000 ... WebAny star that is more luminous than the Sun, but has the same temperature as the Sun, is a(n) ____. giant Careful measurements reveal that a star maintains a steady apparent brightness at most times, except that at precise intervals of 93 hours. the star becomes dimmer for about 2 hours.
