the surface of the star.
actually, it depends on the color of it's chromosphere. as you get deeper into a star, it may change color due to it's temperature, but what you see on the outside would be a different color. The chromosphere would hide the inner core of the star.
the temperature of antares star is 3100 degreeC
the temperature of the pistol star is over 7,500 to about 10,000
The temperature of the star when it dies is 350 degrees celsius
the temperature of the pistol star is over 7,500 to about 10,000
the temperature of..an white dwarf star is 10,000
The colour of starlight reveals the temperature of a star by wavelengths in the electromagnetic spectrum, to give a measuring tool for star temperature.
A white star has a temperature range of between 7,500-10,000 K. A blue white star has an even higher temperature range, and a blue star has the highest.
Spica actually consists of two stars very close together. Both are hotter than the sun. The brighter primary star has a temperature 22,400 Kelvin, and the secondary cooler star is 18,500 Kelvin. In comparison, the sun has an effective photosphere temperature of 5,778 Kelvin.
Star Arcturus has a temperature of around 3,700 to 5,200 Kelvin.
you can tell the temperature by its color
Scientist and astrophysicists have recently discovered a star that has an outer temperature of 80 degrees, so yes you can in fact touch this star, if you had a space ship that could actually travel to it, for more info about this star watch one of the more recent episodes of the universe
