O-type stars are among the hottest stars in the universe, with surface temperatures ranging from approximately 30,000 to 50,000 Kelvin. Their intense heat causes them to emit strong ultraviolet radiation and gives them a blue hue. These stars are massive and short-lived, often ending their life cycles in spectacular supernova explosions.
Neither - Eltanin is a K type star
Enif is a class K2 orange giant star.
Yes - Sirius is a blue-white star - the hottest type of star there is.
Cursa is a binary star system consisting of a B-type star and a fainter star. The B-type star is a hot, blue-white star that is more massive and luminous than the Sun.
Auva is a main sequence star of spectral type A0V. It is a hot, white star that emits a lot of ultraviolet light.
I read on Wikipedia that O-type stars can be a milllion times brighter than our Sun.
A K type star has a surface temperature ranging from about 3,500 to 5,000 degrees Celsius. It is cooler than stars with earlier spectral types (such as O, B, and A stars) but hotter than stars with later spectral types (such as M stars).
Achernar is a type B star, specifically a B6 V star. It is a hot, blue-white main sequence star located in the constellation Eridanus.
an o-type blue star has a less length life than a g-type sun like star, this is because a the larger, hotter star, (the o-type blue star) uses its fuel (converting hydrogen into oxygen) quicker, so the correct answer to your question is the o-type blue star.
Spica is the brightest star in the constellation Virgo.It has a spectral type of B1 and has a temperature of 22,400oK
The spectral type of a star (OBAFGKM) are based on spectral emissions and have no real relationship with size.
Delta Herculis (Sarin) is a star in the constellation Hercules.It is a type A3V star and will have a temperature of between7,500oK and 10,000oK
