An O-type star is a hot, blue star of spectral type O in the Yerkes classification system employed by astronomers. They have surface temperatures in excess of 30,000 kelvins (K). Stars of this …

The closest O-type star to Earth. Zeta Puppis (Naos) 1,080 ± 40: 1: O4If(n)p: 2.24 - 2.26: Gamma² Velorum (Suhail al Muhlif/Regor) 1096 +26 −23: 2: O7.5III: ... O(H)6f: It is the central star of …

An O-type main-sequence star (O V) is a main-sequence (core hydrogen-burning) star of spectral type O and luminosity class V. These stars have between 15 and 90 times the mass of the …

Blue stars are typically hot, O-type stars that are commonly found in active star-forming regions, particularly in the arms of spiral galaxies, where their light illuminates surrounding dust and …

O stars are hot, massive stars. O stars are characterized by the presence of hydrogen (H), neutral Helium (HeI), and singly ionized helium (HeII) in the optical spectra. Other spectral features …

Class O includes bluish white stars with surface temperatures typically of 25,000–50,000 K (although a few O-type stars with vastly greater temperatures have been described); lines of …

2024年5月28日 · O-type stars, with their immense luminosity, mass, and temperature, play an indispensable role in the astrophysical realm. Their formation from the gravitational collapse of …

An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers. They have surface temperatures in excess of 30,000 kelvins (K).

The characteristic properties of type O stars – including spectra, mass, and luminosity – are briefly described, followed by notes about a few well-known examples.

O-type stars are the hottest and bluest of the main spectral classifications. O-type stars on the main sequence have the highest masses (greater than about 15 solar masses), shortest …
