What color are the stars?
The color is, perhaps, the most easily measuredstellar characteristic. It can even be identified by eye. Of course, this approach is considered rude. Therefore, scientists use special photoelectric and photographic receivers sensitive to different parts of the spectrum to accurately measure the color of the star. They allow you to get maximum information about what color stars in the universe.
It is worth noting that the color of such a heavenly body,how the star depends on its temperature characteristics. The most hot are white and blue stars. Objects of a yellowish shade (like our heavenly body - the Sun) are less hot. In turn, the coldest stars, astronomers call celestial bodies with a reddish tinge.
Many stars are not limited to a specificcolor, combining several shades. So, if Antares is a bright red color, then, for example, Arcturus can boast a yellow-orange "appearance", and Rigel - white and blue.
