Which star has the highest surface temperature quizlet?

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 star 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.)

Which star is the hottest star quizlet?

Blue or white are the hottest and red is the coolest. Our own star, the Sun, is nearly in the middle of both the temperature and luminosity scales relative to other stars.

Which of the following colors of stars have the highest surface temperature?

The color of a star shows its surface temperature. Blue stars are the hottest, followed by white, yellow, orange, and red.

Is star hotter than Sun?

The sun’s surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit). That is why it is red — red stars are cooler than the sun, blue-white stars are hotter. Betelgeuse is, however, much bigger and brighter.

What 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 correct order of stars from hottest to coolest?

Summary. Stars exist in a range of colors: red, orange, yellow, green, white and blue with red being the coolest and blue being the hottest. A star’s color indicates it’s temperature, composition and relative distance from earth.

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 group of stars has the hottest star?

If a star looks red, that means its surface temperature is approximately 2,500 Kelvin. Just for comparison, our Sun, which actually looks white from space, measures about 6,000 Kelvin. The hotter the star, the further up the spectrum you go. The hottest stars are the blue stars.

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 are the 7 spectral classes of stars?

Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M.

What is the surface temperature of the star?

Hot stars (such as Rigel, which has a surface temperature of T = 15,000 Kelvin) emit more blue and violet light than red and orange light. Thus, hot stars are blue. One way of classifying stars is by their temperature; stellar temperatures run from about 2500 Kelvin to about 50,000 Kelvin.

What is the hottest color?

No matter how high a temperature rises, blue-white is the hottest color we are able to perceive.
