The color of a star therefore provides a measure of its intrinsic or true surface temperature (apart from the effects of reddening by interstellar dust, which will be discussed in Between the Stars: Gas and Dust in Space). Color does not depend on the distance to the object. This should ...
What type of star cluster has more red stars? What color is Arcturus? What color is the exosphere? Which star is hotter: Rigel or Aldebaran? Why are the brightest stars in the sky generally not the hottest stars in the sky? What is the brightness and the temperature of planetary nebul...
Scotopic (night) vision cannot see the full color that would result, but we can use color as a natural way to depict the various types of stars and their surface temperature. This is done in three steps. First, a relation between the astronomical color index of a star (the difference ...
Stars are classified into groups. From oldest to youngest and from hottest to coolest, the types of stars are: TemperatureTypeColorFahrenheitCelsiusOBlue45,000-75,00025,000-40,000BBlue20,800-45,00011,000-20,000ABlue-white13,500-20,0007,500-11,000FWhite10,800-13,5006,000-7,500GYellow9...
In search of star colors 来自 Semantic Scholar 喜欢 0 阅读量: 21 作者: D Malin 摘要: Efforts over the past century to see and interpret the colors of stars are recounted. The eye, being most sensitive to green and yellow wavelengths, rarely sees stars as blue unless this color is ...

1.The color of a star is measured and quoted in terms of itscolor indexbut basically depends on surface temperature: the star will radiate predominantly blue, white, yellow, orange, or red light in descending order of temperature (seespectral types). Only the brightest stars have recognizable ...

The disk model of Shakura and Sunyaev (1973) and Novikov and Thorne (1973) is used to calculate temperature distributions and integrated spectral fluxes for disks around a typical white dwarf and a typical neutron star, under the assumption that each element of the disk locally radiates as a ...
Atmospheric abundances in post-AGB candidates of intermediate temperature Detailed atmospheric abundances have been calculated for a sample of A-G supergiant stars with IR fluxes and/or high galactic latitudes. HD 172481 and HD 1... A Arellano Ferro,S Giridhar,P Mathias - 《Astronomy & Astrophysic...
