Which star has the highest surface temperature? Spica, with a spectral type of B1 (the closest to O in OBAFGKM), has the highest surface temperature.
Which of the following stars has the highest surface temperature?
Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
Which color stars have the highest surface temperature quizlet?
Consider the four stars shown following. Rank the stars based on their surface temperature from highest to lowest. (Notice that temperature is related to color, and follows the order of the colors in the rainbow: Blue (or violet) stars are the hottest, while red stars are the coolest.)
What type of star has a high temperature and high luminosity?
What type of star has a high temperature and a high luminosity? Blue Giants 19.
What type of visible stars is the coolest?
A red star is the coolest, but still is about 5,000° Fahrenheit! Our sun is yellowish-white and the surface is about 10,000° Fahrenheit. The hottest stars are blue, and can be as hot as 200,000,000° Fahrenheit at their core!
What color is the coolest star?
Red stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
Which star has the lowest surface temperature?
Which star has the lowest surface temperature? Antares, with a spectral type of M1 (the furthest from O in OBAFGKM), has the lowest surface temperature.
What star has a temperature of 6000K?
The hottest stars emit much of their energy in the ultraviolet and appear to be electric blue, like an arc-welder’s torch. The star Sirius is a good example of a blue star.

What is the general relationship between temperature and star brightness?
What is the relationship between luminosity and temperature for stars on the Main Sequence? The brighter it is, the hotter it becomes.
What star has a higher luminosity and lower temperature than the sun?
Although the star VY Canis Majoris in the constellation Canis Major has a much cooler surface temperature than our sun, this star’s sheer size makes it a super-luminous star.
Which color star is hottest?
Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.
Which stars last the longest?
Red dwarf stars make up the largest population of stars in the galaxy, but they hide in the shadows, too dim to be seen with the naked eye from Earth. Their limited radiance helps to extend their lifetimes, which are far greater than that of the sun.
What is the name of the coolest star?
One way that stars are categorized is by temperature. Since the temperature of a star can determine its visual color, this category scheme is known as spectral type. The main categories of spectral type are M, K, G, F, A, B, and O. The coolest stars (red dwarfs) being M, and the hottest stars being O.
What is the coolest main sequence star?
Red dwarfs are the coolest main-sequence stars, with a spectral type of M and a surface temperature of about 2,000–3,500 K. Because these stars are so cool, spectral lines of molecules such as titanium oxide, which would be disassociated in hotter stars, are quite prominent.
